JEE Main 2009 — Motion In One Dimension Question with Solution
JEE Main 2009
Question
Consider a rubber ball freely falling from a height 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

and after the collision, .
(parabolic) (straight line)
Collision is perfectly elastic then ball reaches to same height again and again with same velocity.
