    I got all the same answers except for c which i got as (5root2)/3 which is probably wrong.

    Oh and for the first question I got a = 4
    HOLD UP! Same! For c and a! Holly **** ive never been more glad to read somebody else's answers 😂😊

    My answers:
    Q1) Acceleration: 4 ms^-2 (p = 2, q = -8)
    Distance = 11/3 m

    Q2) R = 784
    P = 4900
    d = 58.1 m

    Q3) c = 10/3

    Q4) Distance below AD = 0.830
    Couldn't work out the angle

    Q5) R = 5g - something cos^2theta
    F = something * dg*costheta*sintheta

    d = ~1.94

    Q6) lambda = 30/7
    v = 10.4 ms^-1
    73.3 degrees below horizontal

    Q7) e = 1/14
    No collision because they're moving the same speed in the same direction

    What was 1b actually telling you to do? I thought just the distance travelled when t=3 but didn't understand the wording

    The distance travelled between t=2 and t=3.

    Same, i found the wording confusing. I think its the distance traveled between t=2 and t=3 ? Thats what i did anyway ?

    Unofficial Markscheme:

    These were mine (didnt see someone else posted)

    -----------------

    I saved my answers

    4
    23/3 distance

    4900 and 784 for P and R
    53.1 distance after engine switched off

    10/3 for value of c

    1.04 for distance from AD.
    161°

    Didnt save the long expressions, take moments at A and resolve vert and horiz. Yiu generate P from m(A) and you sub that back in to R(up) and R(-->
    d=2.56 (I changed this last minute, made a mistake) --moments question

    4.3 for speed? 163° bearing

    Speed of A 3/20u (left)
    Speed of B 21/20u (right)
    e=1/14
    They do not collide as rebound velocity is 3/20u

    Looking back I got the exact same as nitromeguy except I may have put 5 for a, I'm not sure as I did the calculations on a different calculator. I think I may have just taken away the wrong number and only have -1. Relief

    Edit: never mind I did get 4 haha, my coefficients added together to get 5. So 2t^2-8t+11 for v. Anyone else?
    Edit 2: **** I also forgot to square root 109 for speed. I also got 73.3 for the angle of the velocity at A.

    The distance travelled between t=2 and t=3.
    Should be between 3&4?

    **** no im wrong! Ffs i did 3&4

    Lambda was 42/g, another person in my class I asked got this too. This is 30/7 but if you gave it without g it had to be to 3sf.

    For centre of mass I got the distance from 0 in terms of pi and the distance from AD was 0.830. I just checked and the angle was actually 114, you're right.

    The first question I got 5 for a.

    c was 10/3.

    The last question e was 1/14 and the speeds were 3/20 u and 21/10 u.

    I have a load of values in my calculator but can't remember the questions so if you wanna say what you got I can check with mine. Not sure how accurate I was overall lol
    I agree with all of this. For q 1, p=2, q=-4, r=11
    The distance was 11/3

    0-1 is 1st second.
    1-2 is 2nd second.
    2-3 is 3rd second.

    The first would've been 0-1 so 3rd 2-3

    Got all the same , just one thing, the angle in 6b is 73.3 I think , a typo may be?
