1. The problem statement, all variables and given/known data A ball is dropped from a 100 feet and has a 90% bounce recovery. How many bounces does it take for the ball to travel 1854.94320091 feet? 2. Relevant equations -None- 3. The attempt at a solution I know the ratio is .9 and the 'a one' value is 180, so I plugged those values in this equation that is the equation for a Finite Geometric Series: S sub n= a1(1-r^n/1-r) I subtracted 100 feet because that doesn't follow the ratio. then 1754.94320091=180((1-.9^n)/(1-.9)) I got 35 for 'n' but I was wondering if it would be 36 because of the initial bounce?
