    Ahhh at least i was on the right track lol
    I found somwthing like 18m from R then took away 15m (R to Q) :s
    I hope i get method marks haha i had like 3 pages of working for it.

    Anyone get root 5ag for the 4 marker least value of mu.

    Grade boundaries for an A* anyone?
    65 last year. I think similar to 2015 maybe a higher ??

    I got 3.58 of the distance from A but they wanted the distance from Q so i got 7.58

    i got root 5ag, did you say tension at the top was greater than 0?

    I drew the ladder diagram incorrectly, would I get consequential for the part afterwards?

    Some more of what i can remember. Put me out of misery guys haha
    Tension 6g
    Angle theta was 41.4 degrees
    Radius 3. Something m idk. I just resolved horizbtally.

    Least value of tension I just put T=0
    Then u = root 5ag :/

    Ladder 3/4 mu, got a quadratic with tantheta
    Tried to simplify it down. Probably incorrectly.
    Ive probably cancelled wrong or somethibg
    I resolved vertically, horizontally moments about base. Lol idk


    Differential equation i wasnt sure. The constant lambda cancels right?
    V= Ue^gt

    12.7m/s for somwthing
    T=1.26s for force when due south.

    Centre of mass angle like 16.1 degrees??
    I just used the 15cm and the other cm.

    i hope i havent dropped too many D:
    Method marks will save me haha
