    Well K.E is going to be maximum when velocity is maximum, which is when the object is at the midpoint. K.E will be zero when velocity is zero, which is at maximum displacement. Potential Energy = mgh, so it'll be at a minimum when there is no change in height which is at the equilibrium position.
    ah thats clever trhanks

    Why is it on every exam paper topic someone always tells us to stop talking about it... -_-. We want to talk about it, that's the whole point of the thread, it'll ease our worrying while waiting for results day.
    i agree with u !

    Edit - This is the fixed version now.

    Unit 5 is up, Unit 4 will come later.
    Ill also be making a thread for both the papers (So its easier for people to get to them), but I guess the discussions should stay here.

    Edit.
    Skannan:
    I also applied for EEE (firmed with UCL). Shame maths went terribly otherwise I may have had a chance.
    what is your offer and what grades do you think you are going to get?

    Well,the super minimum grade i could get is 60/80.
    I just need 75/100 for each A2 module.

    thanks for the mark scheme fredbraty, i agree with all your answers except this one,

    Q17) H0 = 1/(12*(3.15*10^16))=2.65*10^-18

    you missed of the 12.

    thanks for the mark scheme fredbraty, i agree with all your answers except these ones,

    Q10) F is inversely proportional to the square of distance so it can't be option B, it has to be A,

    and Q12 b ii) a=a0 e^-lambda t,
    lambda = (ln 2)/8 so lamda*t=24*ln(2)/8
    therefore A0 = A*e^lambda t
    =1.5*8
    = 12 MBq
    10. B says proportional, not inversely proportional. Or if that's not what you missed, then the question is asking for the incorrect statement :p:

    thanks for correcting me i thought the question was asking which one was correct,so i said A was correct,

    the exam board trick u all the time, i have only realised the question 11 about the mouse says horizontal in part a and then says vertical in part b

    and the question about the medical tracer, it uses days in part b and then uses hours as unit of time in part c

    edexcel physics is so annoying, when your in exam stress you miss out these key details.

    :yep: :yep: you are correct!
    We already said that it was wrong in another thread,probably you missed it.
    How did you do?

    i realised now i missed lots of marks because the question were worded tricky, like q11 b i didn't read the vertical bit, if i did i would have used a=9.81

    the radioactivity question, they use different units for time in different part of the question, so i messed that up.

    oh well the exams are i think i will 60 or above. hopefully thats more than an A. i am guessing A is going to be 54-56, somewhere around there.
