Asked by Dan
This is a four part question, I need help with the fourth part.
1. I found the Gravitational Potential Energy of a gymnast at her maximum height above a trampoline to be 400J.
2. I found the Kinetic Energy of her just before she makes contact with the trampoline to also be 400J.
3. At maximum stretch of the trampoline (at the bottom of the motion) i found the sum of the elastic and gravitational energy of her to also be 398.75J. (And the kinetic energy at this point is 1.25J to make a total of 400J)
4. What conclusions can you draw from the answers found above.
Any ideas?
Thanks in advance.

And what exactly does Conservation of Energy mean?

hahaa.. funny.
I had to show the calculations for each step. So are you suggesting that I just state that this proves the Conservation of Energy?

yes, that is the point of the problem.
