I thought it was far too easy, boundaries will be sky high

more like an m1 paper

is there ecf in m2?

Just by looking at what you posted, that must have been like the easiest paper in the history :O

For question 4b, the vertical distance DG isn't y, it's root3-y. because y is the distance below AB and the total distance is root3.

EDIT: Apologies, I hadnt seen that you wrote the vertical distance (below AB) as root3-y, looks like we are on the same page after all, sorry about that

Easiest M2 paper I have ever seen. Defo 74 because I left my acceleration in vector form and you didn't but I assumed I didn't need to do that... Meh. 74 minimum
9. Re: M2 Jan 2012 Edexcel - Post exam discussion - Solutions and paper in first post
for the last question V should be 8.49 instead of 6 which you took?
10. Re: M2 Jan 2012 Edexcel - Post exam discussion - Solutions and paper in first post
I feel sorry for anyone who made a numerical slip in this paper. Is it possible for the grade boundaries to be as high as 73 for an A*? Especially considering it was much easier than June 2011 which had 71 for an A* and in January it's mainly the cleverest students taking the exam.
11. Re: M2 Jan 2012 Edexcel - Post exam discussion - Solutions and paper in first post
Does it matter if you put 44 degrees instead of 43.9?
And I put the magnitude of the acceleration just in case, but don't they expect it to be left in vector form unless they ask for magnitude?

Exactly the same. It didn't say magnitude it just said find the acceleration so I left it as a vector...

I hope I don't lose it lol because 75 will be 100 and 74 will be like 95 lol
14. Re: M2 Jan 2012 Edexcel - Post exam discussion - Solutions and paper in first post
is there Extra carry forward please tell me?

What:O,how clever?
16. Re: M2 Jan 2012 Edexcel - Post exam discussion - Solutions and paper in first post
I left the acceleration in vector form! was it supposed to be the magnitude??
17. Re: M2 Jan 2012 Edexcel - Post exam discussion - Solutions and paper in first post
Acceleration is a vector, so you don't have to state the magnitude right?
18. Re: M2 Jan 2012 Edexcel - Post exam discussion - Solutions and paper in first post
Dammit, in my eyes apparently -1 + c = 1 leads to c = 0

Hopefully not more than 2 marks gone for that, I need a min of 90 on this paper to save me from having to get that on fp2/fp3!

Same if It's fine to be left as a vector I got 75 too...
20. Re: M2 Jan 2012 Edexcel - Post exam discussion - Solutions and paper in first post
Arsey please lol! Is it fine in vector form?
