Momentum and CollisionHard
Question
A ball is bouncing down a set of stairs. The coefficient of restitution is e. The height of each step is d and the ball bounces one step at each bounce. After each the ball rebounds to a height h above the next lower step. Neglect width of each step in comparison to h and assume the impacts to be effectively head on. Which of the flowing relation is correct ?
Options
A.
= 1 - e2
= 1 - e2 B. = 1 - e
= 1 - eC.
D.
