Question

A rubber ball is dropped from the top of a building, which is 40 ft. above the ground. Each time the ball hits the sidewalk, it rebounds 77% of its previous height. How high will the ball rebound after its sixth bounce? Round your answer to the nearest 10th.

8.3 ft.
10.5 ft.
10.8 ft.
1,230.0 ft.

Answer 1

I think it's 8.3

Answer 2

Yes, that's correct

Six bounces means that the reducing factor occurs six times.

Final Height = Initial * (0.77)^6
= 40 * 0.208
= 8.3
