2-37.

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 10 feet. Homework Help ✎

How high would it rebound after the first bounce?

How high would it rebound after the 12

^{th}bounce?How high would it rebound after the

*n*^{th}bounce?

Find the rebound ratio by dividing the rebound by the initial height.

Multiply the new initial height by the ratio.

10 · 0.555

5.55 ft.

Multiply the initial height by 0.555, twelve times.

10 · (0.555)^{12}

Remember that the initial height is 10 feet and the ratio is 0.555.
