Pretty worried for tomorrow, been focussing on my other exams too much D:

For an A* in maths is it 90% across C3 C4 and M2 or just the core modules


Just C3 and C4

And yeah same here, Ive barely done any M2

Please can someone help me with question 6 on the M2 June 2006 paper?

I have attached the mark scheme.

http://www.srepapmaxeeeerf.org/A%20Level/Maths/Edexcel/zzzz/M2msJune2006.pdf

The thing is, apparently there is a particle of mass 'm' at B, yet there is no normal reaction and I don't understand why.

Okay quick question :redface: in the textbook,
example 8 page 69, shows that the F used in work done is the resultant force.
however on example 2 on page 64, for F, that isn't the resultant force? I'm confused. (as in they didn't do 96=(F-R)x12

This links to question 3 in the Jan 09 paper, they had a positive force, and a large resistive force (and acceleration) but when asked to calculate the work done against friction, the mark scheme just shows friction x distance
(it doesn't seem to take into account the other force at all!)

Please help D: i'm so confused now lol

A. Work done against friction.

Distance x friction x R = 50 x 4/7 x 10g = 2800 j

B. You can use F = ma to get acceleration then use a suvat.

Force = 70 - uR = 70-56= 14

14 = 10a. Therfore a = 1.4ms

a=1.4
u=2
v=?
s=50

then from there you can work out v.

Whilst we're all on the Jan 09 paper can someone explain 4b and in 5A how come the distance for Y in the semi-circle is -8/pi rather than positive?

I figured 7c out :grin:

You use Distance = speed x time.

For Q. d= 1.25u x t You get the speed of Q by substituting e into one of your previous answers

so t = 4/5 d

Now you do particle p.

1/2u x 4/5d = Distance travelled from the point of collision which is 2/5d.

Distance from collision to wall = d

so d - 2/5d = 3/5d as required.

Edit: Any idea on part d?

I am so ready for this exam.

I'm just giving it a glance and I'm think calculate speed of Q after hitting wall using e, then making a suvat on both P and Q to find distance?

In that question you have to set your own positive values, even if you pick down as negative It should work out

would it be required to use triangle of forces? or can you just resolve and solve normally lol?

We don't have anyone doing M2 this session so I will not be able to get hold of the paper immediately; as soon as I get the paper I will do some solutions.. could be on the weekend but may not be until Monday.

Arghh, I was doing the M2 solomon papers on www.freeexampapers.com and now suddenly it says there is a torrent, and now I can't even access them >_>

Anyone know anywhere else I can find some other practice/solomon M2 papers? :\

Edit: I meant trojan not torrent lol >_>

I haven't taught it for 6/7 years or so. I am thinking of giving myself an A2 FM group next year as I am getting rusty.

If your M1 knowledge is sound, M2 really isn't that much more difficult.

On the CoM questions, check carefully it isn't a shape made from rods rather than a solid. Also practise the toppling/hanging parts, they always seem to cause the most problems (is toppling on M2?)

Ahhh thanks, completely forgot about toppling, have never seen a question with it. On that note, I have time for about 3-4 papers before I'm off, so what would you suggest are the hardest?
Didn't see that you had uploaded the boundaries, thanks :smile: . I'll definitely be having a crack at Jan '10 from the looks of it.
