Question

A ball is dropped from a height of 15 meters and it bounces up to 68% of its previous height after each bounce. what is the greatest height of the ball after the fourth bounce?

Answer 1

Note: The problem says "after the 4th bounce" so

we should calculate the height of the 5th bounce.

 

(15m)(.68)⁵ = 2.181 meters
