The rebound of the ball from the height is an illustration of a geometric series
The total vertical distance at the 10th rebound is 60.352 feetThe first five terms of the sum are 16, 12, 9, 6.75 and 5.0625(a) The total vertical distance
The given parameters are:
The total vertical distance when it strikes for the 10th time is the sum of nth terms of the geometric series.
So, we have:
Substitute values for (a), (r) and n
Simplify
Hence, the total vertical distance at the 10th rebound is 60.352 feet
(b) The first five terms of this sum
The nth term of a geometric series is:
So, we have:
Hence, the first five terms of the sum are 16, 12, 9, 6.75 and 5.0625
