    Same as me, got the rest of the paper right by the look of it

    I have no idea what question 7a) was asking but I drawn a graph with know calculate degree from the vector( ~26 , ~64 and ~90) with root 5 from (-i,2j), and I gusee the F2 is 4.3 something
    If you're interested, I believe this is one way of doing 7(a):

    F1+F2=R => ( - i + j ) + k( i + j ) = λ( i + 3j ) I can't remember the vectors given exactly, this is what I think.

    Then equate i components: -1 + k = λ
    Then equate j components: 1 + k = 3λ and solve for k. => k = 5/2

    The person who created the thread should add a poll for how people found it? It'll give a better idea of how high the boundaries will be.

    I got that at first. I think the mistake i made was accidentally taking away the 0.5m to the left of the support on the left when calculating the moments.
    After checking through, i'm fairly sure i got 1.2m and like 42kg

    Q1a) 104 degrees
    Coefficient of friction question 0.727(well at least 0.7 something)
    F2-2.5i,2.5j
    Impulse- 3Ns
    That's all I can remember
    I can confirm that the coefficient of friction was 0.7271966072

    Cheers mate, any suggestion on the boundaries, im thinking 59-61ish?
    if so i could be in line for 100ums
    No worries. Yeah I agree - although I didn't find it too bad I think a few of the questions were tougher than other years. I reckon
    73 - 100ums
    66 - 90ums
    60 - 80ums

    Forgot to do the bearing, but got the force.

    2/4 sound like correct number of marks?
