Been ages since I've been here. At any rate, I need some serious help here. Ok, its from puremaths paper-4, may/june 2009. The questions are attached. And in case you can't get the attchments, well they are questions 5 and 6 from the questions paper. I'm having problems specifically in 5)ii and iii. And in 6)ii, iii and iv.
Okay If I have any more problems I'll write em down. Thank you.

hey astar you uploaded q5 twice :P

Hey thanks astar!
Thanks a lot.
Hmm, that makes sense I guess,though the answers to the first two parts don't match but that's because of a calculation error. But the way you did it is correct. So kudos to you! But dude like where is the answer to number 6? The pdf file entitled number 6 has the same thing as in the other one. Could you please submit that then?
Thanks again
:)
Oh and I have some problems in finding the range and domain of functions and completing the square...help pleeease

here u go question 6
(i) s=1/2 at2
0.36=1/2X0.62
a=2ms-2
(ii) 0.45g-T=0.45X2 (G force-tension=ma)
T=3.6N
(iii) T-mg=2m
T=12m
3.6=12m
m=0.3kg
(iv) v=u +at
0=u+at
u=at
u=0.6a(2)
u=1.2
v2=u2-2gs
0=1.44-2X-10s
s=1.44/20
=0.792m
ask anythn if u need to
