You drop a tennis ball of mass 59.0 g from a height of 2.50 m above the floor and it rebounds to a height of 1.00 m after one bounce. a) What is the coefficient of restitution, ε? b) What would its maximum height be after 4 bounces? c) If the ball was in contact with the floor for 0.040 sec during the first bounce, what was the average force on the ball? (magnitude and direction)?

You drop a tennis ball of mass 59.0 g from a height of 2.50 m above the floor and it rebounds to a height of 1.00 m after one bounce.
a) What is the coefficient of restitution, ε?
b) What would its maximum height be after 4 bounces?
c) If the ball was in contact with the floor for 0.040 sec during the first bounce, what was the average force on the ball? (magnitude and direction)?
d) You are practicing tennis by hitting the ball against a wall. With what velocity must the tennis ball be moving horizontally towards a wall made of the same material as the floor, at a height of 1.00 m above the floor, in order that it rebounds a horizontal distance of 3.00 m before landing? Sketch a picture of this to help solve the problem.
