Look back at the data given in problem 2-20 that describes the rebound ratio for an approved tennis ball. Suppose you drop a tennis ball from an initial height of
How high would it rebound after the first bounce?

Multiply the new initial height by the ratio.
How high would it rebound after the 12th bounce?
Multiply the initial height by
, twelve times.
How high would it rebound after the nth bounce?
Remember that the initial height is
feet and the ratio is .
