Question
Consider a rubber ball freely falling from a height h = 4.9 m onto a horizontal elastic plate. Assume that the duration of collision is negligible and the collision with the plate is totally elastic. Then the velocity as a function of time the height as function of time will be
Options
A.
B.
C.
D.
Solution
h =
gt2, v = - gt and after the collision, v = gt.(parabolic) (straight line)
Collision is perfectly elastic then ball reaches to same height again and again with same velocity.
