A Wilson volleyball falls vertically from the initial height of 2.1 m with no initial velocity to the floor and bounces vertically, reaching the highest point 1.7 m from the floor as illustrated. Take the origin of the potential energy of the ball to be that on the floor. The mass of the ball is 0.120 kg. What is the velocity of the ball just before hitting the floor?
What is the magnitude of the impulse on the ball from the floor when the ball bounces?
The ball is in contact with the floor for 0.07 seconds. What is the average force F exerted on the ball by the floor?
How much kinetic energy is lost in the collision
