    Why did I get 0.2Ns for the impulse question??? Did anyone else?
    I got the same as you

    nope... for bearing it was 90+14= 104
    that aint the question we are talking about

    Exactly, I thought I was missing out on steps man.
    I did 7 lines for q5 (not counting all my crossings out from when I resolved incorrectly at first) and about 3 for q8a

    thats correct. it is the same angle as 45 from the horizontal
    There was an exact same question about this showing the direction of the Force and in that mark scheme it said marked on diagram not written down... But I think they might accept your answer as well.

    I did aswell but apparently that isnt correct.
    I got this. Think the other answer was if you forgot the minus corresponded to the whole of the - d part when you subbed it in

    For those who got 0.2Ns like me on the impulse questions, I got this wrong, the answer is 3 because the direction of the particle becomes negative so it is 0.4*(4--3.5)=3Ns

    I can't remember the order of questions and I may have missed a few out but here are my answers

    1) bearing 104
    Position vectors
    640i + 640j
    2) T = 20.6
    R= 15.45
    3) impulse 3Ns
    4) graph sketch
    Total time = 40 and T was 8.75 or something
    5) coefficient of friction : u = 0.73
    6) (moments)1.2m and 42kg or something
    7) 2.5i + 2.5j
    Speed 13m/s
    8) 11.74 or something
    Pulley - 16.6something at 45 degrees into plane (225 bearing)

    I got 90+45 =135? How did you get it to be 180 to the horizontal if it was a bearing?
