A certain ball has the property that each time it falls from a height $h$ onto a hard, level surface, it rebounds to a height$r h,$ where $0<r<1 .$ Suppose that the ball is dropped from an initial height of $H$ meters.(a) Assuming that the ball continues to bounce indefinitely, find the total distance that it travels.(b) Calculate the total time that the ball travels. (Use the fact that the ball falls $\frac{1}{2} g t^{2}$ meters in $t$ seconds.(c) Suppose that each time the ball strikes the surface with velocity $v$ it rebounds with velocity $-k v,$ where $0<k<1 .$ How long will it take for the ball to come to rest?
