## Homework Statement

A ball is dropped vertically from a height H on to a plane surface and permitted to bounce repeatedly along a vertical line. After every bounce, its kinetic energy becomes a quarter of its kinetic energy before the bounce. The ball will come to rest after time?

## Homework Equations

Kinetic Energy = ##\frac{1}{2}mv^{2}##

Velocity = ##\sqrt{2gRh}## , where R is the fraction of hight ball reaches after every bounce

## The Attempt at a Solution

I could recognize the geometrical series and attempted the solution which gave me a wrong time.
