Problem G.1
A 0.12 kg ball dropped from a height of 2.0 m rebounds to 1.8 m.
(a) What is the change in the ball's momentum during its collision with the floor?
(b) Suppose the ball is in contact with the floor for 0.08 s. What is the average force of the floor on the ball?

The graph above is the force vs. time for some collision on a 0.25 kg ball that is initially at rest.
(a) What is the impulse given to the ball?
(b) What is the average force acting on the ball during the collision?
(c) What is the velocity of the ball after the collision?
Problem G.3
A ball of mass
m
bounces elastically with a wall. The ball's speed is
v
before and after the collision and
q
, the angle the ball makes
with the wall, is the same before and after the collision. It the ball is in contact with the wall for a time
T
, then what is the average
fore of the wall on the ball?
