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. a. List the variables given by the problem:
b. List the formulas you need to use to solve questions c, d, and e.
c. What was the final momentum of the carts?
d. What was the initial velocity of the 0.2 kg cart?
