A 500 kg truck moving at 30 ms strikes a parked 300 kg car they connect together and move forward What is the speed of the car and truck as they move forward connected together after the collision?
It depends on their initial speeds and masses. The speed can be worked out by: mcarucar + mtruckutruck = mbothvboth where u = initial veloicty m = mass v = final veloicty remember u and v are vectors so will have direction! So: 300 * 0 + 500 * 30 = (300 + 500) * v v = 30 * 500 / 800 = 18.75 or "19 m/sec" to two sig figs.
500kg truck moving at 30 ms strikes a parked 300 kg carthey connect together and move forwardwhat is the speed of the car and the truk as they move forward after the collision?
This is a conservation of momentum problem. Total momentum after collision = total momentum before collision. truck momentum before is MV = 500 x 30 = 1500 kg m/s car momentum before is = 0 (car at rest) truck momentum after = MU = 500 x U Car momentum after = mU = 300 x U SO: 500U + 300U = 1500 ...
A 500 kg truck moving at 30 ms strikes a parked 300 kg car they connect together and move forward What is the momentum of the truck before it strikes the car?
15,000 kg-m/s... momentum=mass x velocity The crashing into the car is irrelevant
A 500kg truck moving a 30ms strikes a parked car with a mass of 300kg they connect together and move forward what is the speed of the car and truck as they move forward connected together after the co?
To get an answer, you must know the mass of the parked car. the parked car has a mass of 300kg
In an isolated system two cars each with a mass of 2000 kg collide Car 1 is initially at rest while Car 2 was moving at 20 ms What is their combined momentum after the collision?
Their combined momentum was 40,000 kg-m/s: 2000kg X 20 m/s= 40000 kg-m/s.
Apex- 588,000 JWell - energy Is measured in joules - one joule of energy is required to lift one kg by one meter - do the maths and your answer is2000x30=60000 joulesUnfortunately you can't get all of that energy - thing like friction and voscous drag get in the way. Nasty that. . . .
Suppose a train car moving down a track at 10 ms hits another train car that is not moving Explain how momentum is conserved after the collision?
Suppose that 1st car is X-car and the 2nd car is Y-car.Answer: After the collision, car X is no linger moving, but car Y is moving.
A person in a head-on car collision who is not wearing a seat belt continues to move forward at the original speed of the car because of?
Inertia=An object in motion tends to stay in motion until it is acted upon by an outside force
when a car is speeding up how does the forward force and air resistance compare
A 735 kg car moving at 20 ms brakes to a stop The brakes contain about 15 kg of iron which absorbs the energy What is the increase in temperature of the brakes?
kinetic energy = 0.5 x 735 x 202 = 147kJirons heat capacity is 0.45 J/g K147,000/ 0.45 x 15,000 = 21.7777o
A car and a truck have a collision The truck has a mass 8 times the mass of the car if the truck is moving at 60kmhr and the car is stationary how fast do the two move after their inelastic collision?
I will assume that the collision is completely inelastic (that is, the truck and the car coalesce, moving off with the same velocity after the collision). This assumption is crucial as without it, the question cannot be solved if the inelastic collision is maintained.Let the mass of the car be m....
What is the size and direction of the final velocity of the tow cars if a 0.4 kg toy train car moving forward t 3 ms collides with and sticks to 0.8 kg toy car that is traveling in the opposite way?
0.4 kg(3 m/s) + 0.8kg(-2 m/s) = 1.2 kg m/s -1.6 kg m/s = -0.4 kg m/s-0.4 kg m/s = 1.2 kg(v) = (-0.4 kg m/s)/(1.2 kg) = v = -0.33 m/sthe cars are traveling at 0.33 m/s in the direction of the second car.
How fast is moving a 10000lbs truck at 20mph strikes a 2000 lbs car at rest and all the momentum is transfered to the car how fast will the car be moving?
The car can't end up moving faster than the truck. Momentum doesn't affect speed, it only affects whether the truck can move the car. Since the truck weighs more, the car will be moved. If the truck is moving at 20 MPH, the car will start moving at 20 MPH on impact, but unless the truck continues...
their stick in each other? O, o stop it your hood is hurting my trunk. sexual innuendo
The momentum of a 5000 kg truck that is standing still is greater than the momentum of a 3000 kg truck that is also at rest?
A body must have velocity in order to have momentum. The difference is that a 5000 kg truck has more mass and therefore more inertia (Newton's first law). Inertia is the resistance to change in motion and so that's where the misconception of momentum and mass occur.
Suppose a train car in moving down the track at 10ms hits another train car that is not moving explain how momentum is conserved after the collision?
The total momentum in a closed or isolated system remains constant. If the two trains are moving as one after the collision, and were the same mass M each, the total momentum before and after the collision would be the same, ccording to the law. Before the collision, the momentum (velocity times ...
Max speed for every car is different-need to know which and what drive train
“300 km/h” is not velocity, constant or not.It is speed.And, a car having a constant speed of 300km/h could have zero acceleration (traveling in a straight line) to large acceleration due to changing directions.
“300 km/h” is not velocity, constant or not.It is speed.And, a car having a constant speed of 300km/h could have zero acceleration (traveling in a straight line) to large acceleration due to changing directions.
A 1450 kg car is traveling with a speed of 15.0 ms What is the magnitude of the horizontal net force that is required to bring the car to a halt in a distance of 57.0 m?
45mphTrick question but It's actually your going 20 mph
There are two cars one in the front one in the back the one in the back moves forward and the one in the front moves back they both collide and are both damaged which car is most at fault?
Equal. Both vehicles were moving and responsible for avoiding contact.
4 times the impact.The formula is 1/2 mass times velocity squared.
so when the body moves in a straight line the average velocity is equal to average speed.Average velocity would be equal to average speed when the total distance travelled equals the net displacement of a particle.This happens when a particle moves along a straight line in a fixed direction.
Who is at fault when after stopping at a stop sign and looking both ways you pull out and a car strikes your car?
There should be no reason why after checking both ways and seeing no cars approaching that you should be struck by a car on the road that you have just checked.Unless the road is unsafe and there is an obstruction to checking for any cars such as a bend, you have not checked the correctly and are...
The maximum speed of the 1970 Chevrolet C-30 6cyl 137hp is 85 mph.
Why does your 92 Saturn idle at 3000rpm when you are in park and drop to normal after 30 seconds also the car is warm?
I just had that problem with my Saturn. Check your vacume hose for cracks and make sure it is connected. If you don't find any cracks in your vacuum hoses, check the EGR valve. I just bought a 95 SL2 and had problems with the idle also. I was able to take the valve off and soak it in carb cleaner...
First car moves at 60km per hour and second car has half the mass of first car as well as it moves at 120km then which has more mementum and which car has more kinetic energy?
Both car have same momentum and Car 2 have more kinetic energy.
The vehicle would be traveling at 125 mph.
Usually vehicles built like this are destroyed. They are generally not sold because of safety liability issues. The same applies to many of the prototypes built by the auto manufacturers.
You cannot move a car that is not yours from where it has been parked. You might have to look for the owner and let him remove the car.If you're talking about repossession agents, they are NOT allowed to enter or move any vehicle other than the one they are there to repossess.You can move that ca...
The cars used in the Indianapolis 500 are called "Indy cars."
More gas is used when you accelerate, that's why using cruise control is a gas saver, it keeps your vehicle at a constant speed.
Suppose the mass of a car is 1200 kg and the mass of the driver is 65 kg what is the total combined mass of the car and driver expressed with the correct number of significant figures?
If the mass of a car is 1200 kg, and the mass of the driver is 65 kg, the total combined mass of the car and driver expressed with the correct number of significant figures is 1265 kg.
They will be of the same length and size.
A likely cause for the overheating is the thermostat is stuck. The best option when this occurs is to buy a new thermostat and replace the old one.
What is wrong with my car i was driving home and as i was parking it didnt want to move forward i can change gears without stepping on the clutch?
something is wrong with the clutch or something is wrong with the gas pedal. But it depends on the car. It happened the same with me with my 2009 Fararri. If its a car that will work but if its a truck than I dont know
Your car won't start unless you pushed the shift lever forward in park. After a while it would not start in Park so you put it in Neutral to start and that worked. Now it won't start at al?
The Park and/or Neutral switch is out of adjustment. There is a hidden switch that must be engaged by mechanical means in order for the starter motor to be engaged. This is to prevent accidental starting while the car is in a forward or reverse motion gear, which could result in the vehicle movin...
it will have the same ground speed (or very similar), but its indicated air speed, (speed in relation to air molecules around it) will be slower. Unless it is a very fast bee flying in circles within the car...The key to the answer is the frame of reference. To the pilot, his stationary frame of ...
What will happen to the truck and car if a very large truck and a tiny car traveling at the same speed collide head on?
In accident reconstructions, head on collisions where equal mass vehicles come to a stop on impact are virtually nonexistent. Physics says the much lighter vehicle should be carried backwards by the heavier one, but it never happens, the smaller car will go underneath or off to the sideNot sure. ...
well since the truck is a lot heavier the force of the truck will damage the car terribly and then with the force it would push the car back which will make that car hit another car and so on eventually this chain will continue if something stops It or the truck (since so large) will not see the ...
There are many relays in most vehicles and I can't think of any thathave a connection with the exhaust.
A car travels through a school zone at a speed of 50 km an hour was the 30 miles an hour speed limit exceeded?
Yes, the car was traveling at 31.07 miles per hour.
Who is at fault if car 1 is at a complete stop at the end of a parking lot driveway and car 2 is in front of car 1 and begins to roll backward and hits car 1?
As with all legal questions, you should consult a legal professional to protect your rights in regard to such matters.Based on the facts presented, Car2 is at fault. The driver in motion must avoid objects in his/her path regardless of the direction the vehicle moves (forward or backward). Only, ...
Wiki will not help you cheat. Time to get to work.
If the car is on or near the Earth's surface, then it weighs 3,086.5 pounds. (rounded)
How can a fly fly around a moving car and not be affected by the speed at which the car is traveling?
It is affected because the fly is traveling at the same speed as the car and the air inside of it. When you are in the same predicament, like flying on an airplane, you can get up and walk around without being affected by the fast flowing air outside. The same situation occurs for the fly in a mo...
A car leaves from 'A' at the same time as a truck leaves 'b' the car travells at 65mph while the truck averages 40mph which is further from'A' when they pass?

Your car doesn't pick up speed when accelerating after been parked at the Lights it also virabes and drives very slowly?
Check your spark plugs. Check your spark plug wires for crack or being loose. You can check your wire at night for cracks, you shold see it acring somewhere. If your car has a distributor, check the cap for cracks and corrosion on the internal connectors. Check your fuel pressure/ fuel filter. If...
A train goes forwards at speed of 1m's for 20s then Stops goes backward at 0.5m's how far is the train from its starting point?
depends how long the train has being going backwards at 0.5m's,an the train didn't stop after it went backwards,ever changing answer
300Km/H. To solve it, simply divide both sides by 40, multiply by 60 to get the speed/hour, and there you have it. The speed of a car that travels 200km in 40 minutes is 300km/h
There isn't a direct relation between cruise speed and displacement. The Rpm at cruise speed is more related in that a high torque big block can run at a lower rpm than say a 4cyl. at cruising speed. In a legal stand point, the speed limit would be the answer. The transmission and gearing are mor...
If your car is impounded with a 30 day police hold what is the process regarding notification before they can sell your car at a lien sale auction?
Different states have different laws on this issue. In some states, if the police have the car on hold, the impound yard cant charge storage fees until after the hold has been taken off. (I dont understand why the police would hold it for 30 days, that's not reasonable) But, the impound yard shou...
A car travels 100 miles east in 2 hours and 30 miles north in one hour. What is the average speed of the car?
average velocity = miles/hours = (100 + 30)/(2 + 1) = 130/3 ≈ 43.33 miles/hour
Why not using uranium in cars even a kg of uranium is enough for the lifetime of cars as fuel its cost is also less?
Because people will be afraid of possible radiation leaks. Also, the amount of money that refiting all of the car factories is money that car componies dont have, so its a good idea, but i dont see it happening any time soon.
The average speed is 40 miles per hour.
What is wrong with a 1997 SC2 that starts and idles OK until the transmission is in gear and the car is moving then the engine speeds up until the car stops moving and the transmission is in neutral?
If the transmission is in neutral and the engine is racing would indicate that your throttle body cable is binding somewhere. Check the assembly, check by the gas pedal. I have checked with a dealer on the same problem. I have a 96 sc2 and it does the same thing. They told me it idles down due to...
Who is at fault when there is a 3 car collision and car 1 speeding hits car 2 going in the same directions and car 2 hits car 3 heading in a different direction?
It would be car one's fault because he was the one who collided with Car 2 causing it to lose control and hit car 3.

When an emergency vehicle is on official business, it has priority over all other vehicles. Be patient and wait for the emergency to be over.
If you hit a car in park from behind at about 5 or so miles an hour and the car moves does that mean the transmission busted?
No, I would not think it would do any damage to the transmission of the car you hit. That is not to say that it is not possible, just unlikely.No if it a manual transmition it is impossible because if it was left in gear it would move the engine and if it was automatic there is some movement if t...
Axles can be found connected to the wheels of your car and responsible for bearing the entire weight of your vehicle.They also help to drive your car and in most vehicles are an important part of the steering system.The CV joint is what connects the axle and wheel together.
Zero. Acceleration = change in velocity/change in timeAs you see the conditions are not met for acceleration to be taking place.
could be steam from a leak caused by the accident in the coolant system or smoke from a transmission cooler leak they are both up in the front of the car.
head lights would be the least of ur worries if u had a car that could travel at the speed of light cause u wouldn't have a car cause it would turn to energy.-foxtrot3092- !!!END OF STORY!!!
A good reason TO use a moving car as a reference point would be, in good driving conditions it is recommended to stay at least two seconds behind the moving car ahead of you.A moving object can not be used a a reference point because it has no fixed position.
What does the velocity of car A which is traveling at 50 ms West appear to be from your frame of reference?
Depends entirely on your frame of reference!If you are in a car traveling along side it at 50 ms, the car will appear to be standing still.If you are going the opposite direction at 50 ms, it will appear to be traveling at 100ms.
When buying a used car from a dealer and they issue temp tags does the dealer insure the car for duration of the 30 day tags?
I am a used car dealer in GA. You are responsible for insuring your vehicle before it leaves the lot. You may not understand: While the tags are temporary, they are yours, not the dealers. (Dealer tags are something entirely different, and only for cars the dealer owns). Temporary tags are actual...
A passenger in a Taxi opens car door at a department store and car going around Taxi at high speed hits Taxi door just as the door is opened Who is at fault Taxi driver passenger fast Taxi driver?
The passenger because he should have looked for cars before he opened the car door.
Probably above 35 mph. Depends upon the weight of the vehicle and tire foot print. This is quite a bit of water on the road so it probably would hydro fairly easily.
A car engine provides a motive force of 700N when the car is moving at its top speed of 40ms1 How much work does the car engine do in each second What is the engines power output help?
Work= F x d= 700 x 40=28000Power = work / timeif you want to convert this to horse power:1HP = 745 Wattsfrom the data that you have provided the hp is around 37
If a car that is being repossessed is at a residence of someone else and a vehicle is behind the car to be repossessed can they move it lawfully?
No. Absolutely not. If they enter a vehicle they do not have an order of repossession on, they've committed a crime. They may enter the vehicle they are there to repossess, and only the vehicle they are there to repossess.
False- since trucks are bigger they have more mass and since it takes longer to speed up, it takes them longer to slow down.
If a 16-year-old living in North Carolina moves out of their house are they allowed to keep the car they got as a gift for their birthday even if the car is not in their name?

At a constant speed there is no acceleration. Acceleration describes a positive change in speed meaning to go faster. Deacceleration describes how fast something is slowing down. But at a constant speed of 60mph there is acceleration or deacceleration.
it does not matter whether it be a car, a bike, an aeroplane or a snail 100km is 100 km so yes the bike and car would be the same
its answer will be 6 hours as car travlling 50 km per hour
What causes a noise in the car after you turn it on and then after 30 seconds it turns off by itself?
This will be a guess, but most Nissan trucks, after you first turn the key to ON, before starting the engine, the electric fuel pump in the tank will turn on and prime itself. It turns off when the fuel pressure rises to normal
If something is traveling at a "steady" speed, it can't be accelerating.
It's a reasonably simple calculation, so without showing the working, a 30mph crash into a solid object is at the same speed you would be going if you were dropped from 8.62 metres (28 feet 3 inches) which is probably the height of a 2 storey building.A 30mph crash head-on into another car doing ...
