Edexcel Mathematics: Mechanics M3 6679 01 - 17 May 2017 [Exam Discussion]

Where did you get this from?

For 0<=x<=4 the acceleration is acting in the direction of x increasing. From this it wouldn't make sense for the velocity to be zero when x is 4. Past here the particles is decelerating because the acceleration is acting in the direction of x decreasing. Therefore the particle is going to come to rest at some point past x=4.

I meant to type x=4, instead of a=4. Thanks for your help. I see it clearly now. I should probably draw a diagram in future.

Oh right, I see.
Yeah trying to visualising the situation is always helpful with these sort of questions.

Thanks again completely augmented Kinematics <3

In general does anyone know which modules we should have completed before M3:

I assume C3 C4 and M2.

But has anyone came across any questions applying FP2 concepts?

Unlucky, are you planning on retaking?

No you won't need any FP2 for M3.
All C1-C4 and M1-M2 knowledge will be assumed.

Fluctuating around 65 marks a paper, not as refined as Id like to be atm - theres always sub-sections of a question or two that throw me off.
Hows everyone feeling? Less than one month to go now :O

Going to try to learn the whole book today

indifferent. it is nice to have a module before break, but it would make more sense to do m2 first but w/e.

Are we guaranteed a question on chapter 1 btw.

Like fp2 it is quite predictable what will come up - but for m3 will we anticipate 6-7 questions inclusive of chapter 1.

Im pretty sure that we will get atleast one question for chapter 1 - not sure if it is
100% guaranteed, but not done a paper where one has not came up yet so..
I presume the format is 1 question from each chapter and then 1 or 2 questions on whatever chapter(s) edexcel want - obviously that is quite ambiguous; I agree with you in that it is not as predictable as Fp2

Can I ask you both, have you found any good online resources for Chapter 2.

Going over it again, and I am finding for questions like the worked examples I am making slight mistakes probably due to lack of complete understanding.

Ik exam solutions doesn't really do M3 :L

It's not an online resource but A2 AQA Physics textbook explains hookes law fairly well.
