Yeah i got it, thanks !

I got to this, what's next?

What change of variable are you referring to? Could you please start me off with the first step?

Is my equation for Q3 right? If so how do I go about solving it?

I don't understand sorry

Is this correct? How do I take the integral in the next part?

So far, I have this: For Part ii) I know that: mgh = xmgsin(theta), but I don't know how to go further

I have 10 mins left, I would really appreciate it if you would help me in a hurry just this once. Please.

I don't know what that means, or how to do that.

I tried mv^2/r = mg and mr''= mg. None of them are working

What forces should I use to try and solve the second part.

Is my second derivative right?

This is all I have, I don't know what to do after, I've been stuck for 2 days, and its due in half an hour.

This is what I have so far, please need urgent help. I don't understand and know what to do. For the first part, I got a really long answer, for the second part I am trying in terms of mv^2/r = mg, or mg = m*(answer to first), but I am getting nowhere. PLease help
