Look back at the data given in problem 5-18 that describes the rebound ratio for an official tennis ball. Suppose you drop such a tennis ball from an initial height of 10 feet. Homework Help ✎
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.
10 · 0.555
How high would it rebound after the second bounce?
Multiply the initial height by the rebound ratio twice:
(10)(0.555)(0.555) = (10)(0.555)2 = 3.08025 feet
How high would it rebound after the fifth bounce?
Remember that the initial height is 10 feet and the rebound ratio is 0.555.
