Edexcel M2 - 17th June 2016 - Official Thread
I hope you find this very useful as a directory for resources and a help desk for any questions about M2 homework, the exam and last minute tips! There are some extremely able people on here, who will be very happy to help - use this to your advantage!

Exam Date
Friday 17th June 2016 pm - 90mins

Exam Info/Guidance
M2 is a step up from M1 - although some of the topics are the same, it is more complicated and it's easy to make small mistakes that can cost you marks that you may not be able to afford to lose.
The topics are listed as follows:
Kinematics
Centres of Mass
Work, Energy and Power
Collisions
Statics of rigid bodies

Resources
Exam solutions videos for M2
Edexcel A-level Maths section
Various M2 resources
MyMaths
MrBartonMaths Applied Module stuff
MadAsMaths M2 Booklets

Past Papers/Practice Papers
Edexcel M2 Past Papers
OCR M2 Past Papers
OCR MEI M2 Past Papers
M2 Solomon Papers
Bronze/Silver/Gold Practice Papers (Bronze = easy, Silver = intermediate, Gold = hard)
Chapter Practice Questions for M2

Hopefully this thread has enough resources to help you gain top marks, and enough questions to last a lifetime. If you ever (unlikely) or think you will run out of questions, buy some really old textbooks off Amazon for 1p and you will hopefully never run out of questions.


Good Luck!

creds to jamestg for the format

No problem, share it around other maths forums and hopefully we'll be able to get it going i know how you feel though, the mechanics modules are the worst ones for me!

I have a question regarding work done. Sometimes they use the total resistance force x distance to calculate work done but other times they use forward force x distance to calculate work done. How do u know which one to use. E.g. for question 5 june 2013 they used resistance force x distance

Can all questions be solved using moments and resolving up/down ? Or is it necessary to sometimes use triangle of forces?

Would my solution to this question get full marks? I got the correct answer but I took moments about a different point that eliminates the need for an additional step but it's not in the mark scheme.Name:  ^47D2CBDB327667A3889B62A2CF25B7ED16DF7F8D7725F2B9BD^pimgpsh_fullsize_distr.jpg

Find the momentum after impulse and divide by m giving you12i+8j. And you should know the rest.

There is a better way to look at it via triangles where you can use the cosine rule. Much better to do it this way so you understand what's going on.

what paper is that from
i think u have to find the angle the impulse makes with an axis and the angle the velocity afterwards makes with the same axis and find the difference between them

Size:  41.7 KBAnother question, surely when the particle is moving perpendicular to its original motion, and its horizontal speed is the same, its vertical component is just (-)original vertical component? In this case this would be -20, but in the mark scheme they have -11.25. Any idea why?

It won't be perpendicular then. Draw yourself a path that is very steep at the beginning (not approx 45 degrees) and you'll realise this.

But on the question it specifies that it is perpendicular?
