    I can't find a thread for this, so I've created one myself. I'm sitting the exam for the first (and last, barring any unfortunate events) time. I've put all my revision energy into C3 and C4, since those are the ones required for the A* grade, so I may be a little rusty come tommorrow, but there is little pressure on this module as I should have gained enough marks from the pure modules anyway.
    Now off to revise ladders leaning against walls, and other moments stuff, as I've just realised I haven't touched those topics since July :p:

    How did you find it?

    something over 3ag +2/3 for the vertical circular motion one?

    It was a relatively difficult paper in my mind but included all the hard things I had revised.

    the last question was rudy hard..i didn't a bloody clue how to prove v was at a max when x was some sort of value..did you do that bit?

    What did you think of the centre of mass question?

    My teacher told me afterwards that we could complete the square to do it, although there was another way.

    The centre of mass question was fine.

    v=max therefore acceleration = 0 so upwards forces = downwards forces.

    weight of man = tension, then find the extension from there (9.8) and add it to the natural length (22)

    9.8 + 22 = 31.8

    can you remember what you got?

    i think i got 8.2 and 11 for the co-ordinates

    Not really, sorry. Although those numbers seem slightly familiar.

    Was the angle 70.9 for horizontal circular motion question?

    Yay I got 70.9 Less worried now because when I got it I thought it looked pretty weird... the particle will almost be moving at right angles

    I think I differentiated, and put it equal to zero. It came out as the answer (31.8) I think, so I'm assuming that worked.

    For the centre of mass question, I got (8.2, 11), or the other way round.

    There is an easier way, you could just have differentiated the equation for velocity to find acceleration, then put that = 0.

    (at least I hope thats allowed)

    glad the general consensus here seems to be that it was a really hard paper! there was WAAAY too much core maths in there
    maybe they'll lower the grade boundaries?


    or else im going to fail.....

    I feel exactly the same, nobody else in my college took it though so I had no idea how anyone else found it
