A ball with a mass of 2.0 kg is dropped from a height of 1.5 m. The ball hits the floor and bounces back to a height of 1.1 m. Use energy conservation wherever possible to answer these questions. (a) What is the speed of the ball just before it reaches the floor initially? (b) What is the speed of the ball just after it leaves the floor? (c) How much work is done by the floor? (d) The coefficient of restitution of an object is defined to be the ratio of the rebound speed to the impact speed. Calculate the coefficient of restitution for the ball. (e) What is the impulse experienced by the ball while in contact with the floor? (f) If the ball is in contact with the floor for 5.0 ms, what is the average force exerted on the ball by the floor?
