Homework Statement
A ball is dropped from a height of 24m and rebounds to a height of 16m. If each time it rebound two-thirds of the previous height, find the total distance traveled by the ball.
Homework Equations
The Attempt at a Solution
I thought this might be a problem approaching infinity even though the ball cannot bounce infinitely. So i used the equation a/1-r where r was two-thirds and a was 24. That didn't work; however, when I added 24 and 16 then divided it by 1-r i got the correct answer, 120m. Was this a correct procedure? if not could you explain which procedure should be used in this case.
