i tihnk i did the probability question and i got stuff in the ratio of (forget the exact numbers ) but it was in the form of ninths.. like 1/9:2/9:4/9 .. ?? anyone else get something like that?Poad said:For the mechanics question about what does 'b' represent, I put water resistance.
And meh, I didn't have much time to actually *think* about that probability question. I got 3:1:1 for that ratio.
I think its either water resistance or the velocity of the current.ronnknee said:Actually I think velocity of the current is the correct answer now =\
i think delta was a constant...not sure though...zonda1 said:did anyone have trouble with 8 b) i) ?
i couldnt remove a delta from the answer
yeh my ratio was 1:1:9, i had some ninths in there somewhere..fozzster22 said:i tihnk i did the probability question and i got stuff in the ratio of (forget the exact numbers ) but it was in the form of ninths.. like 1/9:2/9:4/9 .. ?? anyone else get something like that?
yeh thats what i did and yeh it was lotsa work haha, probably not the right methodcookiemonsterz said:i didnt do the ratio for the probabilities.
did you have to find the limiting sum as n-> infinity for the aswers in i)-iii). seemed like too much effot for one mark.
hopeing 60% zzz. went too slowly..
Its terminal velocity, sub t = infiniteronnknee said:Actually I think velocity of the current is the correct answer now =\
yeahhhh does anyone have the paper pls?cccclaire said:Could someone who was allowed to keep the paper scan it and post it up?
It would be muchly appreciated.

i dunno if im right but for18836165 said:Can someone tell me what they got for the probability questions, i probably f'ed it up.
