A student using an air track with two carts records the result of an inelastic collision. One cart has a mass of 0.2 kg and the other a mass of 0.4 kg. They moved off
together at 0.2 m/s after the collision. The 0.4 kg cart was initially at rest.
-What was the final momentum of the carts?
-What was the initial velocity of the 0.2 kg cart?
-If the collision lasted 0.02 s, what force did each cart exert on the other?
