EXTRA CREDIT PROBLEM DUE 12-11

A basketball is dropped from a height of 30 feet.  Each time it strikes the floor, it rebounds to a height that is 72% of the maximum height before the bounce.   If the ball is allowed to continue to bounce up and down, what is the total distance that it will travel before it comes to a stop?  (weird concept here, but does it really ever come to a true "stop?"... hmm...)
