Q1. A rubber ball of mass m = 0.739 kg is dropped from a height ho = 4.73 m, and it rebounds to a height hf = 3.66 m. Assume there is no air friction.

a) Find J, the magnitude of the impulse exerted by the ground on the ball.

b) If the ground exerts an average force of magnitude F = 727 N on the ball, find contact, time the ball was in contact with the ground.

c) Find ΔE, energy lost during the collision between the ball and the ground. (NOTE: Energy lost is positive.)

Q2. A piston, A, as shown below, has a diameter of 0.81 cm. A second piston, B has a diameter of 3.9 cm. conclude the force, F, necessary to support the 508.0 N weights in the absence of friction.
