- A 0.20-kg model railroad car moving with a speed of 0.20 m/s is struck from behind by an 0.42-kg model locomotive moving along the same line with a speed of 0.50 m/s. If they stick together after thecollision, what is their velocity?If I shoot a rubber bullet horizontally at a stationary toy car from behind and the bullet sticks to it will the momentum be the same as what the bullets intial momentum was or will it be diffrent since the bullet is now stuck to the car because they are both together now and two diffrent weights. The velocity of the rubber bullet is initally 36m/s and the toy car weighs .2kg and the rubber bullet is .00001 kg. Is there a momentum for the car and the bullet or just one as a whole and if there is indivduals mometum what will be the momentum of the car and bullet with the info given when the bullet hits and sticks and starts movign the toy car?
