The mother of all q 10's is the pulley one in 2003.....................I hate that q
That one is alright. You need to be pretty good at manipulating algebra to get that one right. In saying that, I lack some skills in that area. I lost 2 marks in that very last question where I failed to prove that it was maximum length but I got the rest which was okay.
The above question that I answered is not that hard too but you definitely need to analyse the question in the bigger picture. The hardest part about this question, in my opinion, is to work this question out from the first part and the rest should be easy.
But the 2003 question definitely needs some serious algebraic manipulative skills, which are what I lack in my opinion. Apart from that, it's damn straightforward.
