    Zacken Do you only take the square root of something to find magnitude if vectors are involved? So for example if the question did not involve vectors and it asked to find the magnitude of the force exerted on a pulley, would you or would you not take the square root of whatever answer you get?

    Am I right in saying that if it says find the magnitude in a question that isn't about vectors, do you find the size/value of whatever it is that you've been asked to find the magnitude of?

    I'll have a go at them, thanks! Any others you recommend?
    Trying Jan 2014 IAL at the moment, and it definitely isnt easy so that might be a shout.

    when you say magnitude cant i use F=MA if the weight is given
    and is M the weight or mass?

    Take moments about D making sure to remember that the distance will be the length from one corner to the other corner (use Pythagoras to find the length of the diagonal).

    anyone got predilections of what is likely to come up ?
    i would always expect a big pulley question. First question is usually collissions.
    And you would expect either one big vector question or a small vector question and a medium vector question

    how long does it usually take for you to complete the M1 exam, do you have a lot of spare time to check your answers?

    i am not sure which paper it was but it asked to find the resultant magnitude i think, mass was given and above that acceleration is supposed to be found
    and F=MA was used

    I would prefer no vectors but I don't think that's gonna happen XD

    You have to draw a diagram and stuff its complex check mark scheme
