How did we all go? Physics June 2011

[soopertaco]

for the momentum question, im guessing EK was conserved from A to C, therefore velocity at C = velocity at the bottom of the hill??

indeed.

[soopertaco]

Can anyone remember question 1?

I remember all you had to do was use F=ma=(2500)(0.5)=1250

I can't remember but did you use the whole systems mass? just to be sure D:

I was surprised at how easy Q1 was.

i was like SCORE!!! this exam's gonna be a breeze. i jinxed myself

lol

thankgod, cant wait for some worked solutions....

That was surprisingly easy. If you knew your theory, you would've aced it. No real challenging questions if you compare them to exams in previous years.

Bullshit! It wasn't necessarily ridiculously hard, but much much harder than previous years.

RAN OUT OF TIME! As did most people in my class.
And forgot how to do apparent weightlessness.

Shame'd so hard, leaving that exam was like this: http://www.youtube.com/watch?v=bZLamQWlqJA

OMFG
Placed Vout over the resistor BUT I used 500ohms....
NOOOOO

[forumguy]

Will you get any of the 3 marks for that?

Hope so...
At least 1

I made the exact same mistake, I think we'll get two marks/3. Seeing as the only mistake we mate was the wrong resistor value?

[Blackrat]

I drew Vout over the thermistor, and the 500ohm resistor... are we not allowed to do that??
Cause it'd still work, right?

thats what i did, it looks right at first, but when u decrease/increase the temperature.... =(
how many marks do we get if we drew vout over thermistor and used a 500ohm resistor?

I did the same thing. I reckon we might get 1 mark which would be reasonable since we didn't quite grasp the concept.

Sounds like scaling will be greatly in everyonrs favour this year

[Blackrat]

oh crap.... I did it for temp's LESS than 20degrees, I even checked what wound happen if the temp. went BELOW 20 degrees
bugger.
