    Couldn't do the vectors one but just resolved horizontally and vertically in hope for 1 mark

    You had to show the change in magnitude of velocity was over 6ms-1

    Did anybody else think that Centre of Mass question was absurd? It was so... qualitative. I have perspective on what moving the centre of mass down by... what, a quarter of a metre? Does to the initial mass. I just guessed it went from 90kg to 80kg. Probably way too much. I haven't a clue.

    The one where it was show the resultant vector is greater than 6ms. I had a long number, 8.xxxxxxx

    I think I got 8 something. I definitely didn't get 6.something.

    **** I messed this paper up.

    Yeah, I assumed distance of the modern one was the 1.5m + an extra 0.2m to ensure he made it over the bar then I said the old method would be the same as the new but + about 0.1m for the difference in height of centre of mass, it was such a stupid question, not sure if that is correct.

    The mass wont change only the height does i think mine was about 150j

    Was that when you had to estimate the jumpers mass

    I got something like 8.3 aswell, I formed a right angle triangle by putting the vectors tip to tail and then used Pythagoras to find the resultant vector.

    I don't know if it was correct but I just wanted to get some working out done on the paper in hope of getting some method marks.

    Does anyone know where we might find some sort of unofficial markscheme for this? Also any ideas roughly what mark we'll need to get an A in this paper?
