How many bounces can the ball make

Reference no: EM13336599

A ball is dropped from the top of a 6.10m tall building, falls straight downward, collides inelastically with the ground and bounces back up. The ball loses 10% of its kinetic energy every time it collides with the ground. How many bounces can the ball make and still reach a windowsill that is 2.44m above the ground?
