Question

A rubber ball is dropped from a tall building at a certain height. It is found to raise only 90% of its previous height. If it is dropped from the top of 25m tall building, to what height would it rise after bouncing on the ground 2 times?

Answer 1

Falls 25 m

Bounces first time to height 0.9(25) = 22.5 m

Bounces second time to 0.9(22.5) m; you can calculate this final answer.
