Anyone think this enough for an A*? M2: 75/75. M3: 68/75. FP2: 66/75?

Looks like it :wink:

F*ck edexcel. Got around 50 for this and had to d1 straight after and it was impossible to finish in 1hr 30.

Did question 5 ask to take moments about A? How many marks would you lose for finding R in terms of F?

For the last question I made an arithmetic error that caused me to get the wrong speed for B in part a meaning I used the wrong value for the speed of B in part b and c how many marks would I drop bearing in mind my method using impulse etc was correct in part b.

No you had to find R and F in terms of d,g and theta. They didn't ask you to take moments about A I'm pretty sure. I took moments about B correctly.

Sorry, I didnt use F in my answer to part ii) so I thought you meant the force P.
I wrote your F as 'uR' (with u being the mu symbol thingie), im pretty sure it wont matter as that IS the total horizontal force.

He's not. Edexcel told him he can't do them anymore.

SAME. Got b slower than a so didnt collide and some screwed up e. Frustrated think i missed one of the constants of the masses somewhere

I estimate that I got around 62:
on 1b, integrated between 0 and 3, so I'm estimating 2/5 marks, M1 and A1 for the correct integral.
on 6b, I stupidly used 4 instead of 3 for the horizontal component, so I estimate 2/7 marks, M1 and A1 for the correct vertical component.
Lost the last 5 marks on Q7.
Any estimates of what 62 would get?

Does anyone know how much question 2 was worth?

Looks like you're being quite harsh with your marking (which is always a good thing).

62 would definitely be an A/around 85 UMS.

The mass of the cyclist was 80kg not 800kg

This is it, however the second equation was P = 12.5R - 12.5(80gsintheta) because the cyclist was moving down the hill.

So you get

3P = 12.5R + 12.5(40g)
P = 12.5R - 12.5(40g)
2P = 25(40g) = 1000g
P = 500g = 4900N

Wouldn't P be in watts tho, not in newtons?

He's not allowed to do them anymore. Edexcel are being right ****ers for making the papers hard as balls and telling Arsey that he's not allowed to do the model answers.
