5. A golf ball that weighs 0.5 N is dropped from a height of 1.5 m. Assume that the golf ball has a
perfectly elastic collision with the floor.
a. Construct a motion map for the golf ball from the time it is dropped until it reaches its
highest point of rebound.
b. Determine the time required for the ball to reach the floor.
c. What will the instantaneous momentum of the golf ball be immediately before it strikes the floor?
d. What will be the change in momentum. (Ap) from the instant before the ball collides with the
floor until the instant after it rebounds from the floor? (Illustrate with a vector diagram.)
e. Suppose that the golf ball was in contact with the floor for 4.0 x 10's. What was the average
force on the ball while it was in contact with the floor?
