me too! except i saw there was a triangle and just couldn't remember how to find the area of it...Bi0mic said:i totalled myself in that area one :|, completely skipped the fact there was a triange and went for 2 integrals ...
i put 1 : 2root3becany said:the ratio of MY:AC?
i got like...1/root3 : 2
i put that as well ~~ yaygreeninsanity said:i put 1 : 2root3
for 9bi) i think i got t=2s as wellManagore said:i) was 2, ii) was 4. When A=4, V has been reduced to 0 and when v=0, we have a turning point, aka a maximum.
Yes. [comment]...[/comment]timbo_lives said:does anyone know if HSC markers do "error carried forward" when marking the maths paper, if so, thatll save me quite a few marks!!!!

it was not t = 2 because that was an ACCELERATION vs TIME graph.. not VELOCITyomg_a said:nono, t=2 is the max because it's where a is 0. the secon2 part is t=4 furthest displacementbrcause at that point v=0, and after that goes backwards.
igot the second part wrong but my dad's a maths teacher and he said that's how you do it.
That's what I got... hmmm.smallcattle said:I think i got 27
45-18
