    Would you say that it's weird that I got 80 and 84 in C1 and C2 and then 91 and 85 in C3 and C4? :woo:
    Yes, and well done! ... did you work much harder in the 2nd year or something?

    Let's do the math here.

    Bus weighs 12 tonnes = 12192.56 kg (2dp)
    Speed limit = 30 mph = 15.64 m/s

    Impulse at point of impact with OP = m(v-u) = 12192.56 x (0 - 15.64) = 190691 Ns

    Such a redistribution of linear momentum would be easily large enough to result in death :yep:


    :rofl:
    Why do you think the OP will bring the bus to rest during impact?

    :rofl: :rofl: :rofl:

    I hadn't considered that. Ok, lets assume that the OP has a mass significantly larger than the bus and is also in constant motion

    And also that she is perfectly spherical {as well as the bus ofcourse}

    Ahem. I would just like to point out, I don't plan to step in front of buses and so I doubt I'll be getting run over by one anytime soon =]

    Most people who get run over by buses don't plan to be. You could be the victim of a tragic accident :no:

    Maybe she is? :eek:


    Anywho, the point was to model them both mathematically to show that being hit by a bus will create a large change of momentum. I never said the maths had to be correct. QED.

    Thank you and yes I did work harder. But that can't be it though because I retook C1 in that year (and worked just as hard for it) and came out with 79

    I guess bruceleej is right, experience peaks at the very end and you stop making silly mistakes.

    Maths is awesome. :cool:

    It's surprising how much you can improve in a year or two. If you work hard enough, by the end of Year 13 an A could easily be on the cards.

    My maths teacher told me that if you tried dividing by zero on a calculator then the whole world would explode because it couldn't handle it.

    He was wrong

    I'd blame grade boundaries. Looking at the 2006 June papers, the raw mark needed for an A varies from 71% to 85% - that's quite substantial.

    No, you'll just have to work slightly harder. To assure you, there's hardly a correlation between your GCSE grades and what you get at A/AS-level.

    Actually, Ramadulla, the product moment correlation coefficient between GCSE Mathematics UMS and AS Mathematics UMS is 0.86 (that's a strong positive correlation).

    Oh why did you have to say that :cry:

    Now the OP will have schizophrenia.
