I think you had to work out all the different cases. Eg: 4W, 3W 1L, 2W 2L, etc, etc. Then work out how many of those arrangements yeiled more points for the home team. Which i think was 31. Hence probablilty = 31/81 (i hope)

I got 81 ways for part i. 0.0144 for part ii. 31/81 for part iii. Any takers?

i didn't think you could get an answer bigger than 1 because the max height, depth and width was 1.

I did about half of a) & b). I also got n +- sr(n) for a & b int 8bi. I got 0 for 8biv. Anyone else?

Did anyone else get 1/2 units^3.

You cannot use: W = Fd W = mgh F = ma Time dilation Mass dilation You had to use the GPE formula. 0.75MJ is the correct answer.

Thankyou. In that case the answer is 0.75MJ and everything else is wrong. (1.75MJ will probably get you some marks.) BTW: I got the 4u joke about de moivre. very funny... End of discussion.

I agree. I also took the question to mean from 20000km to 80000km. Now, for all those people out there. You can't use GPE = mgh, you can't use F=ma and you certaintly can't use mass or time dilation. You had to use the GPE formula. The question was ambiguous but if you took it from 10000...
