    Just wondering if anyone has some rough solutions for this year's 2016 AH Mechanics. Here's a link to the paper:https://drive.google.com/file/d/0B3Y...ew?usp=sharing

    Hi there

    Here are my answers to the paper (sorry no workings, so no solutions to 'show that', 'prove' etc. questions)
    Anyone have different ones?

    1. 8.14ms^-1
    2. P=40sqrt(3)-32, Q=40-32sqrt(3)
    3. 27 joules
    4. y=2x-e
    5. Amplitude = 7.55mm, 198 full oscillations
    6.b)i) 20
    6.b.ii) Straight line
    7. Maximum speed=21.3ms^-1, KE increase = 2048J
    8.b) 3+1/(x-1)-2/(x+3)+3/(x-2)
    9.a) 29
    9.b) Coefficient of friction stays same on all of the track.
    10.a) (1-5t)/2
    10.b)i) 26.6 degrees
    10.b.ii) 0.6
    11. x-coordinate is 3.2, couldn't work out y in exam
    12.a) Speed=86.4kmh^-1, direction=N 15.3 degreesE
    12.b)i) Direction of wind now against direction of travel
    12.b)ii) 24 or 25 minutes???
    13.a) 2570 units cubed (3.s.f)
    13.b) 11.3 units
    15.b) x=0.25e^(-4t)-0.05e^(-20t)
    15.c) 0.16m
    16.b) 48.2 degrees
    17.a)ii) sqrt(5gr)
    17.b) 5r/3
