# 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?

## 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...

## 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.
