(a) At time t = 2 seconds, the two carts collide in a perfectly inelastic collision (meaning they
stick together). Calculate the final velocity of the 500-gram cart after this collision.
(b) The collision takes place over a time period of 0.5 seconds. Draw and label a graph of the
velocity of both carts as a function of time for the time period t = 0 to 4 seconds (still
assuming negligle fricton).
