A 0.5 kilogram rubber ball is dropped from a height of 3.0 meter above a hard concrete floor. After striking the floor the ball bounces up to a height of 2.0 meter above the floor. The ball was in contact with the floor for 0.05 second.
Compute the change in momentum of the ball during the interaction with the floor.
Compute the magnitude of the average force of the floor on the ball during the interaction.
