Welcome, ooh. (Right... that sentence just looks weird. :rolleyes: )
I'm afraid that I have no idea what an 'IB student' is, so I'm just tossing out something that popped into my head while reading your post. I've never actually seen any project done on the physics behind bungee jumping, and there's certainly a lot involved.
