Questions
A body from height h is dropped, if the coefficient of restitution is e, then calculate the height achieved after one bounce.
detailed solution
Correct option is C
When a body falls from height h, it strikes the ground with a velocity u=2gh. Let it rebounces with a velocity v and rise to a height h1. v=2gh1⇒e=vu=h1hClearly, h1=e2hTalk to our academic expert!
