Edexcel AS/A2 Mathematics M2 - 17th June 2016 - Official Thread

Was the com question in metres or centimetres? Would you lose a mark for using m as a unit instead of cm?

I got 15 too but what u had to do is work out the displacement between t=2 and t=3 because it said in the third second. Annoying question yes

I thought it was metres?

I don't remember what it was and what units I put but they wouldn't take off a mark for that? That's a physics thing. I know in reality it's a big difference but I'm hoping they count it as a misread. I probably put the correct units. I'm just really worried about M2. I really want A* in further.

Their value of g is accurate to 2sf (well for some parts of the world? For you to be able to leave it as a positive constant it would have to have g in the answer but since 30/7 has no g value and we used g in the suvat equations, we can only leave it to 3sf max. I'm hoping you're right because I left it as 30/7. What did everyone else leave it as?

I left it as 30/7 but I’m kicking myself for doing so - I'm almost certain that it should be to 2 or 3 s.f. In the preamble for most of the examiners’ reports it comments on this issue and it even reminds us on the front of the papers. I think final answers with g should either be left in terms of g (i.e. 42/g in this case) or to 2/3s.f.

Beautiful. Thank you.

Does 6 marks for question 3 seem particularly generous to you?

For question 6 you say the angle was 73 degrees but your diagram makes it look like it was 73 degrees upwards. I think it was 73 degrees downwards because I think the vertical velocity at A was -10ms^-1

Fair enough, I was just trying to show the size of the angle, forgot about whether it's up or down haha. Sorry!

Hi guys,

So I'm supposed to be revising for C3, but I remembered all the questions from 1-6. I'm really sad, sorry. If anyone remembers Q7 holla at me.

I hope that these are right, but remember, I'm a student just like you guys!

If you have any questions let me know.

I'm very surprised because I walked out thinking I got a D, as I convinced myself that I did everything wrong because the answers were all almost fractions and such. But I got pretty much almost all the same answers ( I reckon at least 57/75)

I felt pretty similar, I thought I'd done badly. I wasn't too worried though because this was a retake for me (I'm an A2 student) I was surprised to see my answers were mostly correctly.

If I got the centre of mass wrong, however did the 2nd part perfectly with obviously a wrong value, do I get full marks?
