A ball of mass m falls from rest from a height of y1, collides with the ground and bounces back up to y2. The collision time with the ground is ?t. A) Determine the momentum of the ball immediately before the collision with the ground. B) Determine the momentum of the ball immediately after the collision with the ground. C) Determine the average force exerted on the ball during the collision. Now let: m = 0.080 kg y1 = 3.0 m y2 = 2.0 m ?t = 0.005 s. D) Determine the numerical value of the impulse of the ground on the ball during the collision. E) Determine the numerical value of the change in the kinetic energy during the collision

A ball of mass 2.25 kg is released from rest at height 5.29 m above the floor. It falls, hits the ground, and rebounds to height 3.19 m above the floor. Assume none of the losses are due to air friction. Find the impulse, in N-s, exerted by the floor on the ball. The sign of your answer will give the direction of the impulse.
