Question

I need help with this geometric growth and decay question

Answer 1

Ball drops 12m in the first step.

It rebounds 9m and drops back 9m covering 18m in the second step.

Total distance travelled by the ball before coming to rest

`\begin{gathered} 12+2(9+6.75+5.0625+3.796875) \\ 61.21875 \end{gathered}`

The total vertical distance would be

61.21875
