Xsanda’s solutions:

1) Car on a plane:
i) v = 22.5 m/s
ii) P = 35.9 kW

2) Particle up a plane:
i) Wd = 8.43 J
ii) v = 10.8 m/s

3 Arch shape:
i) show that: 13a/3π
ii) T = 8.82 N
iii) θ = 10.9º left of upwards vertical

4 Particle around a cone:
i) show that m/6 (2 sqrt3 g - 3 a ω²)
ii) T = 39.6N, V =1.19 m/s

5 Ladder:
i) show that 5W/24 (1+6x/a)
ii) max x = 1.7a
iii) tan = 39/14

6 collisions horizontally:
i) a: 5.5 m/s, b: 8 m/s, both in opposite direction to their original motion
ii) e=3/4

7 projectiles:
i) 18.8m high, 61.1 m AB

That was dreadful. Estimate I've got about 51-52 raw marks depending on method marks.


Well, if there's one thing I'm really good at it's estimating my marks. Got 80 UMS on the dot for this, 51/72! Hope everyone else got what they wanted.

I also got only 84 in FP3 despite expecting 57+ raw marks (should be 92+ UMS), and my friend got 50 UMS which was quite a shock for him. I can only assume that the mark scheme for Question 8 (groups) was extremely harsh.
