5-35.

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 ✎

  1. 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

    5.55 ft

  2. 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

  3. How high would it rebound after the fifth bounce?

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