I've just had a go at part c, see if this makes sense...
Note: for simplicity sake, k[SIZE="1"]1, L[SIZE="1"]1 and A[SIZE="1"]1 refer to the original values in the equations and k[SIZE="1"]2, L[SIZE="1"]2 and A[SIZE="1"]2 refer to part c where the length of DNA is folded in half.

Hi, I need some help regarding an elasticity question I am attempting.
I have done the first two questions and need someone to check over what I've done.
I also need some direction on how to attempt part c, as I'm feeling a bit clueless on where to begin tackling this.
Homework...
Ahhh.. ok! God I feel stupid, I knew I was over-complicating things.
Thanks for replying Kurdt.
So, that would mean for part c that when the ball is returned, the displacement will be 0, using the same principle of part a?
Also, can someone please clarify for me some terminology for...

Q. Jessica and Tammy are playing a game of tennis on a court that is 24m long.
Tammy is standing at the net, so Jessica (who is at the baseline) lobs the ball from near the ground aiming for the baseline on Tammy's side 24m away. She hits the ball at an angle of 60◦...
Hi tiny-tim,
Firstly, thanks for the reply!
I'm finding it difficult to work out what the question was actually asking... I am so new to physics.
so basically if I think of the 30.3MJ per litre at 100% efficiency, I can work out the energy required at 30% efficiency... the thing that...
Hi,
Can someone please check my answers and possibly help with part c; I don't know where to begin on solving it.
