M2 May 2012 Edexcel - Post Exam Thread - Paper and Solutions in the FIRST POSTM2 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
[b]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/show....php?t=1906907
June 2011 - http://www.thestudentroom.co.uk/show....php?t=1618497
The second link has loads of past papers, mark schemes, model solutions etc
Good luck.Last edited by Arsey; 02-06-2012 at 12:26. -

Re: M2 May 2012 Edexcel - Post Exam Thread - Paper and Solutions in the FIRST POSTIt 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.

Re: M2 May 2012 Edexcel - Post Exam Thread - Paper and Solutions in the FIRST POSTIt 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.
