A 50 kg person on a trampoline bounces to a height of 5.5 m. On their second bounce they end up only 4.5 m high. On their third bounce they end up 6.5 m high.
If they just bounced without using any effort, how much energy was lost in the second bounce to sound and heat?
How much energy did the person need to produce on the third bounce (include the amount needed to overcome the energy loss found in the second bounce)?
On the third bounce, you measured the deflection of the trampoline to be 0.25 m. What average force did the person apply to the trampoline to get to 6.5 m high?
