Look back at the data given in problem A-18 that describes the rebound ratio for an official tennis ball. Suppose you drop such a tennis ball from an initial height of
How high would it rebound after the first bounce?
Find the rebound ratio by dividing the rebound by the initial height.
Multiply the new initial height by the ratio.
How high would it rebound after the second bounce?
Multiply the initial height by the rebound ratio twice:
How high would it rebound after the fifth bounce?
Remember that the initial height is
feet and the rebound ratio is .
