Problem
A rubber ball of mass 0.10kg falls vertically and just before striking a horizontal floor it is moving downward at 10m/s. After rebounding, it moves upward at 8.0m/s. The ball is in contact with the floor for 0.050s.
(i) Calculate the change in momentum of the ball during the contact.
(ii) Determine the average force exerted by the floor on the ball and state its direction.
