Question 1089773: a rubber ball is dropped from a height of 25 m and each time it stikes the ground it rebounds to a height of 60% of the distance from which it fell. find the total distance traveled by the ball before it comes to rest. Answer by Edwin McCravy(20060) (Show Source):
Let the first term be the ball's first 25-meter drop PLUS
its 25(0.60) = 15-meter first upward bounce immediately
following. That's 25+15 = 40 meters for the first term.
Each term thereafter will consist of the ball's drop plus
its upward bounce immediately following. So the first
term is 40 meters and the common ratio is 0.6. The
formula for the sum of an infinite geometric series is:
