    Well , it is weird how i can't get 22.5m/s and ended up with 17m/s :/

    Update!!!!! : I found out something.
    You are wrong!

    170 / 10 = 17m/s

    125 / 8 = 15.625m/s.

    ITS NOT LINEAR.
    THE SPEED TELLS YOU THE GRADIENT. IF THE THE SPEED IS DIFFERENT THE GRADIENT IS DIFFERENT. THEREFORE IT IS NOT LINEAR. GOOD TRICK AQA!
    I got 15.625 , I'm not quite sure how though

    Hello everyone, I am an A grade student and I am aiming to get an A* in Additional Science, I have been revising for a long time and was well-prepared for the exams. The B2 and C2 papers were quite straightforward, but today's P2 was not, even though the 6 mark question was pretty easy... If you want I may give some answers, which I think are right, however I HAVE done some stupid mistakes because I was a bit stressed. Thanks)

    THIS IS WHY EVERYONE GOT 17M/S and this is why its wrong
    170/10 ----------> 17m/s
    You cannot do this because the line is not directly proportional on the whole line, it needs to be a straight line to take the gradient, you can't just take the whole line and work out the gradient and therefore the speed if its not a straight line as different parts have different speeds.

    You have to take a section of the line from the steepest part. As this was straight you could work out the gradient.
    The difference was from 125 to 170 over 2 seconds

    SO 45/2----------> 22.5m/s

    It's definitely B, the velocity levels off cause it reached a terminal velocity
    this is probably the stupidest question but I can't for the life of me see why it wasn't A
    the question said the graph should show the velocity of the rocket as it falls until just after it hits the floor
    so surely when it hits the floor the velocity will be 0, and A was the only graph that ended on the x axis

    Dont worry man no one is 100% sure about whether the answers are wrong or right, we might be right

    True, the topic is perhaps the most obscure of all of P2 tbh, but to be fair it was a ridiculously straightforward 6 marker. So much so I suspect there must be more to it.
    yeah, i very mcuh enjoyed P2 and P3's 6 mark questions. For P3 I think i must have wrote down everything i knew about ultrasound and x-rays, i better get all 6 marks, i wrote about 9 points.

    Matt, no need to use that tone, and I'm afraid to say you're incorrect. Charge is measured in ohms.
    No I'm afraid you're incorrect, resistance is measured in ohms
