M2 May 2012 Edexcel - Post Exam Thread - Paper and Solutions in the FIRST POST

M2 May 2012

Overall I thought this was a very hard paper. Jan 2012 was a joke, so they really made up for it with this one.

Q1 Linear kinematics

Fairly easy C2 = 0 was a bit odd

Q2 Collisions

Slighly trickier than normal I would say

Q3 Moments

Significantly harder than normal, it was strange that it was just pivoted in mid-air. Aslo the wording off part b) may cause problems

EDIT - I may have overcomplicated b)

I thought it was referring to a vertical plane because asking for just the vertical force and direction seems too easy (and pointless)... it could of course simply mean up or down

However, for 4 marks, it probably just required 40.1 acting vertically upwards

Q4 COM

a) was okay but b) will be a MASSIVE bloodbath; I can not see many people getting it correct.

Q5 Impulse

Very strange question, this again will cause a lot of problems

Q6 WEP

a) and b) are fine but I think c) will cause a lot of problems

Q7 Projectiles

a) and b) should be okay but I think c) is very tricky

Last few June boundaries were 68, 61, 62, 64, 58 for 80ums

This was a hard paper and I think the boundaries will reflect that, so I will guess at

100ums - 70
90ums - 63
80ums - 56
70ums - 49
60ums - 42
50ums - 35
40ums - 28

This thread will be locked at somepoint and then unlocked at midnight following the Mechanics 2 examination. I will upload the paper and my solutions to this post.

I will do my best to answer questions about the paper but please try to read the thread first so that I am not answering the same questions lots of times.Here are some links to previous M2 threads, they are worth a read and you will see what the common errors were...

Jan 2012 - http://www.thestudentroom.co.uk/showthread.php?t=1906907

June 2011 - http://www.thestudentroom.co.uk/showthread.php?t=1618497

The second link has loads of past papers, mark schemes, model solutions etc
Good luck.

It was horrible, I got 75/75 on Jan 2010 and I thought this was even harder ! I know I lost 6 careless marks, but had zero time left at the end due to how horrific it was !
WORST case scenario - 61/75 (getting no method marks for my mistake questions)
BEST case scenario - 69/75 (I wrote down a reasonable amount of correct working on my mistakes)

Very similar style to January 2010 overall though ?
Probably the same person wrote it.

VILE.

Goodbye A in Further Maths, goodbye Oxford. Hello McDonalds.

It was horrible!!

It wasn't too difficult overall. I left a couple of questions 'til after I'd finished the others so I could have a think about them before rushing into them, but in the end there was nothing in there that was a problem.
