I got 1/2
yep i got that. might be right? I did the concavity test as well. but im glad i can do the trial next year againthe light intensity question was ridiculous.
anybody get a x=1/2 for the max value in last part of q10?
>implying I failedahahaha should have listen huh, I told you guys, start of the year, like 14th January that you would be shitting yourself come trials, you would have been better off with a tutor (mental insurance as some have put it) . Well, enjoy failing lolololol
sorry but u failwas the concavity test necessary for both marks? i didn't have enough time to do it
I also got that!the light intensity question was ridiculous.

that is a kinda shit explaination, you probably won't get the mark. you failed ahhaa.for the particle question when it asked if it ever goes back to origin.
i wrote no as the velocity is never 0 (actually it is but when t= a negative)and for the particle to change direction, velocity has to be 0.
anyone confirm or get something else?

lol well please explain how you would do it. the velocity had a log in it so unless u wanna integrate a log...that is a kinda shit explaination, you probably won't get the mark. you failed ahhaa
i got a 9 aswellI think I got 9
it's easy sonlol well please explain how you would do it. the velocity had a log in it so unless u wanna integrate a log...
yes but to turn around v must = 0 so im saying it doesnt turn around so theres no way of getting to the origin...that is a kinda shit explaination, you probably won't get the mark. you failed ahhaa.
havent seen the question but its possible to turn around and not go back to the origin, massive noobery here.
thankyouanne1010
It is quite correct in rectilinear motion (motion along a straight line) to go back to where a particle started or to go backwards somehow, and it started off moving away from origin, then it needs to reverse direction of motion; for that to occur velocity needs to reduce to 0 before it can become negative.
So what I mean is: particle must at some time have v=0.
obvious troll is obvious, gtfo.that is a kinda shit explaination, you probably won't get the mark. you failed ahhaa.

i said something like this aswellfor the particle question when it asked if it ever goes back to origin.

But I don't think that could equate to a mid 70%'s in the internal mark. I feel so demotivated right now..well, on a positive note, you still have some time(10weeks or so? which is a lot of time if used properly) before the HSC exams
So that's the other 50% that you can still improve!!!
