Hey everyone how did u go?

Anyone get k=-sqrt2 and 2.61 or 2.66 for last answer?

[Edward Elric]

Damn you beat me to it, I found this years exam very accessible, although slightly more difficult than 2013. Multiple choice took so long though, ended up guessing a few. Fuck that vectore Question, but overally descent exam. Lol cant remember sorry, but what was your working out? Because I remember my working out.

No idea what that k question was asking.
I found the exam to be fairly depressing, one of the hardest one I've done (although, that probably came from the placebo effect of being in exam condition and the weight this exam has on my future)
I think i have now developed a phobia of water parks lol. I could not get the last part of the question, and they just have to make it equal to 5 marks too.

yeah i got k=-root(2) but 2.66 only not 2.61 for the last answer. I found the exam pretty fair, I've probably lost 5ish marks on silly mistakes and a few on the d.e but everything else I found okay. Anyone else get stumped by the 3 marks for one stationary point?

If anyone has a copy of the exam, now's your chance to upload it.

Knowing you, you'd get 40+ easily

Thank god there was no vector calculus question on the ER

[arush002]

X in terms of t??

[Edward Elric]

For acceleration, did anyone get 3.97 for 3kg mass, and 4.82 for 5kg mass?

[forchina]

nooooooo....I got k=-2sqr(2)
 

[Mieow]

X in terms of t??

YES! I could only solve it for t in terms of x, and when I tried using my calculator it couldn't do it   

Also with the vector question, it said find a as the sum of the parallel and perpendicular vector resolute, but it took me back to the original a vector. does that mean i did something wrong?

yep

[SunburyCollegeStudent]
