A-35.

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 $10$ feet. Homework Help ✎

1. How high would it rebound after the first bounce?

Rebound height = Rebound ratio · Drop height
Substitute the values you know and solve for the unknown.

Rebound height = $10 · 0.555$

$5.55$ ft

2. How high would it rebound after the second bounce?

Multiply the initial height by $0.555$, two times.

$(10) · (0.555)^²$

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

See part (b).
