How did u guys do ??
2. the last part of the last question was hard other than it was easy?

I Subtracted S from L, Then made an quation and forgot to Equate it to 10 hopefully ilose just a mark or two

how were the other questions??
5. The Moments question ? first Were Show that then Weight of W i gfot it 280. Speeed-Time Graph i got it ummm lemme remember cant remember. xD Wht else was there Momentum and impulse was easy.

why do take so long to reply
1 st question was answer 18
to finm u shoilddivide by 9.8/
7. mmm, i think i had a diff, Varient ? xD my First questoin was Momentum i thnk
8. for the tension of A, the second part of the moments question, i got something like
(1/6 W -40/30)N.
9. wt did ppl get for T in speed time graph
I got 55

Also wt did ppl get for the tension of BC

Wt did ppl get the distance travelled by B in pulleys qs
10. Yeh...T was 55s

For tension i got 12 N after rounding off

and the distance in the pulley question i got till where you get 5.3 and then i didn't know what else to do afterwards so I guess its wrong... : /

anyway what do people think the grade boundaries will be for this paper as it was fairly easy ?
11. i hope the grade boundaries are low, but for example, in june 2007 i think it was, the boundary for an A was 66/75, and this paper was of roughly the same difficulty.
12. hope its low ( fingers crossed )..does anyone know where to get the mark scheme ..official or non official ?

Nope But i Hope its Low.
14. does any one has the paper???? can u pls upload it
15. guys here's what....for the distance question i.e the value of T...it said 'it travels at a constant velocity for T seconds' and not 'upto T seconds'.....so you gotta do like 75-(T+5) for the last triangle....at least that's what i think....this way you get 50 secs and not 55....rest all was ok and i think i rememberr my answers to majority of the questions....lemme know if anyone is interested
16. look it was 50 or 55, I did like u did 75-(T+5) Cant remember the first S= i tink it was 25 ? Cant remember.
17. @Bassiouni-- yes you do the same and find the distance vector between them and then write a pythagorean equation like

i^2 + j^2 = 10^2
18. To clear up the athlete question i'll try and do it by memory but it may be wrong:

s=1/2bh + bh + 1/2bh
500=(1/2 x 8 x 5) + (8T) + (0.5 x 8 x (75 - T - 5)
500=20 + 8T + 300 - 4T -20
200=4T
T=50s

Thats what i got anyway so ya know
19. Yes yers that was it

I got that too.
