    If you get the right answer with working that is different (but still valid) from the mark scheme do you get full credit mark wise?

    Hey guys, I was wondering if anyone had a link to the 2015 M1 paper?
    Edexcel website?

    You too! I'm just going over vectors for 20 minutes on ExamSolutions then I'm sleeping. How many hours sleep are you going to give yourself?

    Force on bottom block will be equal to the weight of the top block and bottom block combined
    Which force? If you mean the reaction from the floor of the lift, they are only equal if there is no acceleration.

    Hey on that Mr. Barton thing you just linked, how come the weight of the lift is 600g + N when N is acting upwards?

    Could anyone explain what you do when one vector is, for example south west of another? I know its something to do with knowing they make an isosceles triangle but still a bit confused on the method. Thanks in advance
    I believe what happens here is because south west is a direction which would have a bearing of 225, and tan 225=1, and tan^-1(i components/j components)=225, i components/j components = 1, so then you just make the components equal one another and solve for the unknown value (if that makes sense?)

    it literally says in the paragraph lol

    "don’t forget Newton’s third law therewill be some ‘equal and opposite’ pairs of forces"

    "If the normal reaction on the man is N newtons then this means that the liftfloor is pushing up on the man with a force of N newtons and therefore theman must be pushing down on the lift floor with an equal sized force of Nnewtons."

    Actually j and i components the other way around sorry!
