Describe 2 or more examples where momentum is reduced by applying a smaller collision force over a longer impact time (in other words, where things “give way” during a collision to lessen the impact force by increasing the time of impact). I struggle a the time :(

Aball with a mass of 275 g is dropped from rest, hits the floor and rebounds upward. if the ball hits the floor with a speed of 2.40 m/s and rebounds with a speed of 1.70 m/s, determine the following. (a) magnitude of the change in the ball's momentum (let up be in the positive direction.)
