Problem
A ball is dropped from a height of and rebounds to three–fourths of the height after each impact. Ignoring air resistance, find the total vertical distance (in metres) the ball will travel before coming to rest. a) b) Divergent (no finite distance) c) d)Intuitive explanation
The key insight is that the ball travels both down and up, and each bounce reaches a predictable fraction of the previous height. After the initial drop, the ball bounces to m, then falls that distance, bounces to of that height, and so on—forming an infinite geometric series. You'll need to sum the distances for all downward and upward segments separately, then add them together.
