kill chem !
Yeah man, I'm gotta motor through business stuff tonight, hopefully get a 90-95HSC mark for it
Then I'ma have more than a week to dedicate to chem. should be good :p hopefully i get an HSC mark of 95 for chem too. Calculating my ATAR a while back ago, I dont think 3U will count but even if I get an E2 I'll have 1 bonus point into my course :p Im ranked 27 in my school outa like 85 kids, and my friend last year (went to our school) was ranked in the bottom 10 and she still raked in a E3 so eh, 2+ bonus points? :D

you change the equation into Rcos(nt-whatever) = -5
then you work it out. I got 1.5 seconds or something like that (i probably solved it wrong knowing myself)
yeah i got like 2. something

For the projectile, 66.97 deg <= @ <= 75 deg. For the rates/plane, the first part could be proved using cos rule and Pythagoras, and for the second part I got something that looks like



Though I might have gotten the signs or cos/sins mixed up.

Found the paper easier than past papers 2011, 2010 etc however for question 14 I couldn't prove that they triangles were congruent! >:O I had the hypotenuse, side but I couldn't prove the 90 degree angle in triangle MXS. Could someone help me with that?
Also had trouble with b iii, my angles didn't overlap i had angles ranging from 15<theta<23? and x>50 for the height equation. AND I couldn't do anything from part C
SO IF ANYONE COULD DO ANY OF THESE QUESTIONS PLEASE FEEL FREE TO LET ME KNOW HOW YOU DID IT
