Thank you very much for your help!

I think it does not start storing energy as she drops? I assumed that the string would not be compressed or stretched for 9.5m down as it is the length of the string.

Sorry, I'm not exactly sure how to use this site yet and the quoting functions so I hope this simple reply format is ok. For the x=4.1m, that was me trying to find the amplitude of the system (thinking back on it however, it wasn't helpful). The fact that there's no elastic energy makes a LOT...

I started off by finding when Fg=Fx: (72)(x)=(31)(9.8) x=4.2193m After this I'm stuck and have a few things I'm confused about: When the penguin's jumping, is there elastic energy? (because the rope's getting compressed? Or maybe not). Also, I know you can use energy conservation, but...
