    i hope the calculation is alright though my ans is different to quite a lot of my fds -o-
    Which calculations?

    i think it was alright, realised i screwed up on the last question with my rearranging but may get the marks for recognizing what to do -__- only aiming for b/c so thought it was okay epecially the large amount of definitions, eassy marks.. did anyone mention elastic hysterisis for the material graphs?

    No hard maths questions. Some of the wordy questions were a little bit picky and I guess I will loose a couple there. Apart from that it was really nice
    what did you put down for the motion question when both A and B are moving ?

    What did you guys get for the radius? 10?

    Rotation but continuing moving in the right direction

    Yeah I got 10 for the radius aswell :/ The volume was 900.... or something so I divided it by 3, then used pi x r^2 to work it out, dont know if its right .
    What did everyone get for the angle the acceleration makes with that slope?

    Uh 11.7? Or 50 something. I just remember the two angles I obtained but not too which question it came from

    Too many definition and wordy questions than I would of liked :/

    Hoping for a lowish boundary for an A

    it was harder than jan. hopefully grade boundaries will bw low

    Yeah this exam went great.. For the two angles I got 11.8 and 59 respectively in terms of question order.

    Also i got 10 for radius in the last one and I stated that a higher density means more mass and thus higher k.e.. is this right?

    Also I got 119 kg for the mass of sledge and rider?

    hmmm... trying to remember more..

    I'm guessing grade boundaries would be 45/46 for an A. I think I got around those marks and usually I scrape A's so we'll see.

    Although test was harder than Jan so it might be 43/44 for an A.

    I got 11.8 for the angle with the sledge. What was the other angle question again?

    the other anglle question was for the vector triangle and i got 45 degrees, i thought that was right but people are saying it was 53 or something,

    what did other people get for the angle?
