A round ball bounces to 2m after being dropped from an undetermined height. To what height will it bounce if dropped from a height 2.5 times as high? (how do u even calculate this problem?). (or is it just a problem that cant be solved?)

If the coefficient of restitution is independent of the velocity at impact, the ball will rise to 2.5 times the height of the ball that bounced to 2 meters, or 5 m. This is usually a good assumption.

The coefficient of restitution of a bouncing ball is the fraction of the kinetic energy that is recovered after a bounce. It equals the fraction of potential energy (height) recovered after each bounce.

you can`t because the height of the ball is higher than the ball bounces

thanks!
