A Bouncing Ball

How would you approach part E of this question?
I am a bit lost as I don't know how to find the total time spent bouncing... Is it linked too the equation for the time between bounce n and n+1?

Not worked the whole question through so I don't have the results of the previous parts, but, yes, you're correct. Time spent bouncing will be the sum from n=1 to infinity of the time between bounces (this is another GP), plus the time for the initial drop, I assume.
