    Think you’ve f’d up tbh cause I’m seeing others get 6.66 so couldn’t have all made the same misltake
    Definitely 6.66, and discussing with a few others in my class had the same.

    For question 2 the value of P is 6.66 because the friction acts up the slope as it’s the minimum force required to keep it in equilibrium

    I got 6.66 and other people did to so not really sure now
    Mate, I got 6.66 and I’m sure that’s right Cus the rest is simple it’s the fact that it said find the least force on P so you know that it was on point of sliding down

    P = 16.4
    Tension in C = 735N Tension in D = 1323N
    velocity of P = 1/4u
    Velocity of Q = 5/4u
    Lift Q part a 3050N b) 6 people
    Yeah I am 100% of 1a and 1b

    hopeful 6 people is right too!

    for question 2, did you guys just find the normal reaction first and then subbed it into the equation for resolving forces down the slope?

    If you didn’t get 5.42 you must’ ****ed up with sin or cos somewhere, maybe done them the wrong way around, I do these questions in my sleep and it was defo 5.42
    I got a different answer if I typed everything separately (13 something) and the 5.42 if I put it in all together - I crossed out the 5.42 rip

    What the actual f was that paper....
    Here's what I got but pretty sure most of them are wrong:
    3.75
    2 = 31.1
    2898
    24
    t= 0.1
    33 people (wrong)
    34.9
    a= 8.2
    Pretty sure I flopped that

    DAMN IT i put 31.1 and i had 6.66 aswell, just guessed and went for the wrong one

    Lift was 6 people no? it was like 6.9... so it had to be 6?

    I got the lift as 7 people as i had 7.76 people so i rounded down
    Same! I feel like we forgot the mass of the lift when considering the Acceleration. How many marks will I loose?
