I'm really quite confused at this question I've just done on Jan 2013 Mechanics paper.
The paper is available to download here: http://tinyurl.com/m93d388.
And the question I don't understand is: 2ii.
What I don't understand is why you take away the total work done away from the GPE?
If someone could shine some light on this for me I'd highly appreciate it!
