    oh well...
    i done it for 10 seconds instead.
    did you only take one value fro the graph? because i think to work out average you need 2?good luck anyways

    I found the distance for 6 seconds and the distance for 8 seconds, then because 8-6 is 2 i simple divided the distance once i took one away from the other. so 45/2 is 22.5. Just because you got an A* Doesn't mean you are correct.


    Where did the 8 and 6 seconds come from? Sorry I can't really remember the question!

    It asked about the change though didn't it? So that would imply subtraction is involved?
    It was change that you were finding from the graph in the first place, no further calculation is involved -the information was obtainable from the single point at 2, you weren't provided with any other information...

    your absolutely wrong mate, it is 22.5 because it was linear and straight at the end and had the steepest gradient, 10-8=2 and 170-125=45 so as your 'a* ' would tell you that equates to a speed of 22.5 m/s

    just 2 different points from the graph so that i could work out how much distance was covered over 2 seconds as beforehand the graph wasn't linear

    What do you think of these revised grade boundaries?

    P2: 48/49 A* (54 = 100 UMS)
    P3: 44/45 A* (51 = 100 UMS)
    C2: 48/49 A* (54 = 100 UMS)
    C3: 45/46 A* (49 = 100 UMS)
    B2: 43/44 A* (49 = 100 UMS)
    B3: 44/45 A* (49 = 100 UMS)

    The roots of education are bitter, however the fruit is sweet.

    Someone please explain this quote to me before it becomes the new gangnam style. Does I think it means what I think it means
    I was thinking that

    Yes the question didn't ask for the focal length, it asked for the change in focal length

    I would say biology should be around 46 for b2

    C2 will be 50-51

    The graph gave you information about the change in focal length -that was the whole point.

    Out of interest- how many marks was this question as I think I missed it out?
    It was a diagram so probably only 1, can't remember though

    Ah right ok thanks I had a bit of a blank moment and for some reason just found the speed at the end of the line (top right) so got 17m/s but I'm pretty sure that's wrong now...

    Can you remember how many marks it was?
