OCR MEI Mechanics 2 (M2) 19th May 2014

I just did this paper and completely messed up, I've been getting As in all of them and just got a C in this

How did you do question 3 i) ii) & iii)

and a lll of question 4 i had no clue

Does anyone understand how to do 1 b on the june 2011 paper?

Does anyone understand how to do 1 b on the june 2011 paper?

Right here are my notes which I just made for answering question 3 for June 2013:

(Just realized that I missed out the units of a few of the forces! It's always worth checking )

thanks mate you're a life saver

do you happen to have 4 b i can look swell please??

Do you want all the workings for 4)b) or just some parts?

workings please

My workings for this question are actually pretty bad. For 4)b)ii) I did a really long method which was so unnecessary but I still got the right answer. Then for 4)b)iv) I actually misread the question and worked out tension-OQ instead of QP, when infact I unnecessarily worked out QP correctly in the previous part anyway Sorry it's not too clear.



edit: Does anyone think there is a harder moments question than Q3 in June 2013, I'd really get some more practise on the difficult moments questions.

good luck everybody! hopefully there will be a lot of nice things in this exam if not, lets all lower the grade boundaries a bit hahah! good luck! thank you everyone for your help

Hmm, I know what you mean, everyone makes silly mistakes, some more than others (I used to have a massive problem with doing it) but the way I got around it in both mechanics and physics, is while you read the question write down the numerical data that you know, or draw the situation if appropriate (and label all the forces if it is a force diagram, that way the examiner knows which forces you used for what), and write down the possible equations you know, and then just think, which equations are most appropriate/simplest in this situation, then work out a series of steps you will use to solve your question. Then slowly go through thinking carefully whether what you are doing makes sense, do not rush! And make sure your working makes sense, and use written comments like state which direction you are resolving, or whether your moments are antiC/W or C/W. Finally once you get to your final answer/answers, consider whether the magnitude and direction seem reasonable, for example someone in free fall is unlikely to be travelling much over terminal velocity (although they might try and catch you out) but if your answer seems a little bit odd, carefully look through your workings, comparing them do what you typed into your calculator. Finally with your final answers, STATE THEIR DIRECTION! you can loose a couple of marks for not elaborating, so if an answer is negative, write it as a positive, then state that it is in the opposite direction (this is where diagrams are especially useful). That's about all the advice on not making mistakes I can give!

I'd just like to thank you on behalf of everyone who has read this and benefitted from it! I'll try to bear these things in mind
