Anyone remember how many marks the distance to the centre of mass was worth?
How much was question 1b worth? (Uk paper)

I did the same mistake... Remember how many marks was this question worth? Part a was 8 but part b?

Think it was 5

5 marks

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


Same dude.
Anyone got centre of mass question
distance to be 1.98 and
angle to be 178
For the angle on the projectile, is it the angle about the horizontal or the angle about north?

I wrote both down as I was unsure

Answers to edexcel m2 uk paper
1 a) 4ms-2 b) 11/3
2) P =4900 R = 784 d= 53.1
3) c= 10/3
4) x =0.83m, angle 113.6
5) a) friction = (5gdsinthetacostheta)/4
Reaction= (5g/4)(4-dcos^2theta)
b) d = 2.56m
6)a) lambda = 30/7 b) speed 10.4 angle 73.6
7) a) Va = 3u/20 Vb = 21u/10 b) e=1/14 c) no since moving at same speed in same direction


i got all the same except 1b i integrated 3-0

same i integrated between 3 and 0 for 1b and for the other question for where therre were kinematics i got the 90 minus (his answer) .

Would i get marks for putting down his answer but not saying it's my answer?
I got 22/3 in question 1 b)
How did u get 11/3?

It was definitely harder than average; the poll so far shows this. Expect lower grade boundaries than usual.
