A steel ball with mass 40.0 g is dropped from a height of 2.00 m onto a horizontal steel slab. The ball rebounds to a height of 1.60 m.

(a) Calculate the impulse delivered to the ball during impact, in N-m. Define upward as positive.

(b) If the ball is in contact with the slab for 2.00 ms, find the average force on the ball during impact, in N. Define upward as positive.
