Question: Consider two cases in which the same ball is thrown against a wall with the same initial velocity. In case A, the ball sticks to

Consider two cases in which the same ball is thrown against a wall with the same initial velocity. In case A, the ball sticks to the wall and does not bounce. In case B, the ball bounces back with the same speed that it came in with.
a. In which of these two cases is the change in momentum the largest?
b. Assuming that the time during which the momentum change takes place is approximately the same for these two cases, in which case is the larger average force involved?
c. Is momentum conserved in this collision? Explain
