Question

A) A ball is dropped from "M" meters above a flat surface. Each time the ball hits the surface after falling a distance, h, it rebounds a distance d, where 0<r<1. Find the formula that represents the total distance the ball travels up and down.
B) Use the formula in part A to find the total distance if M=20 meters and each bounce is two-thirds of the height of the previous bounce.
I think I should be using the Geometric Series here I just cannot figure out how to write out the representing formula. Any help is appreciated.
