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

Personally I think the paper looked weird af but was alright if you applied your mechanics. I can never do centre of mass questions anyways so I probably got that wrong (oh well). Other than that the paper was super non-standard with a lot of weird questions. Also anyone who did FP2 will understand that p,q and r and no longer part of my alphabet as they are disgusting letters and should be killed with fire.

I would think that you would probably lose one or two A1 marks for it, assuming your method was correct (I would think it might be M1A1 for getting the correct integral, M1 for subbing in values and solving).

How many marks was the question where you had to find d=? (the one with the non uniform rod)?

My answers:
1).
a). q=-8, p=2, r=11
b). 11/3m


2).
P=4900w
R=784N
b). d=53.1m


3).
c=10/3


4).
x=0.83m below
angle= 114 degrees


5).
d= 2.56m


6). lambda= 30/7 (4.29)
speed= 10.4m
angle= 73.6 degrees to the vector i (horizontal)


7). A= 3u/20 (left)
B= 21u/10 (right)
e=1/14
no collision as B after wall moves at the same speed as A, hence never meet

Very true, could be either depending on how anal they are. Probably would be fine though actually



No problem dude

Question 1 had 3 parts, part b) was to find the acceleration of the particle when t=3 wasnt it?

Other than that I got all the exact same answers as you ^^ hopefully 90+ UMS

Exactly; I posted it again to complete edothero's list. They match up so it's all good.

Ahh was the position vector lambda(i+j) or lambda (i-j)
