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

Here are my answers to the paper (sorry no workings, so no solutions to 'show that', 'prove' etc. questions)
Anyone have different ones?
2. P=40sqrt(3)-32, Q=40-32sqrt(3)
3. 27 joules
5. Amplitude = 7.55mm, 198 full oscillations
6.b.ii) Straight line
7. Maximum speed=21.3ms^-1, KE increase = 2048J
9.b) Coefficient of friction stays same on all of the track.
10.b)i) 26.6 degrees
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
16.b) 48.2 degrees

I've come across this example in my mechanics textbook... And I'm so confused... I really don't get the working, not even the first line! Could someone possibly point out to me what's going on at each step? Many thanks in advance (HAHA LOL, geddit? ;p) Seriously though, stressing out if this is a very simple concept that I just can't seem to see !
