How was it?

yeah just derived that bad boy.

apart from the spring q on motion though. i think i went alright. Only other concern are explain questions in electronics. they always confuse the hell out of me.

structures was the easiest i have ever seen lol. no angles or anything lol

yeah none of that difficult torque questions (i dont get torque still )

The explain questions for photonics when darker is increase and then increase yea? Coz less light=more resistance=more Vout

When you want the light to go on earlier LDR would increase causing Vout to increase so R must increase to reduce the influence of LDR increase?

Yup, got 5.7degrees and 4J, and 50Nm-1 for spring constant

What do you think the A+ cut off will be for this exam? Lower than last year's 96?

[kenhung123]

ABB

third w was about momentum.. trickkkyy asssss

third was if the collision was inelastic so energy is lost..

i agree with the first ,

but the second one doesnt the light increase since it is at sun set so early would be after noon eg.

Hopefully...........

Without a doubt, lower.

however it was asking about momentum. i thought too that it was asking about the total energy or kinetic energy or something. but it was about momentum. which is conserved despite being inelastic or elastic

well i did the vcaa 2009 exam in 30min and got 84/90 <--no double checking
this year's exam was alot harder, but still possible hoping cut of mark would be around 75ish

I got ABB for the graphs question

and LOL my calculator was in radians moed so i got 6.3 degrees for the banked curve one even though I had the correct working out

And I am really really confused about the 0J vs 4J question. I got 4J, but physics teacher says 0J =/ Such a confusing question =/

And haha I was going really slow at first...I saw i was at question 8 for motion when 30 minutes already passed >.< So I quickened up and finished with 20 mins to go lol...then i spent the last 20 minutes checking motions questions i had asterixed (there weren't really any contentious question in electricity or strctures)

Is it 0J!!! Damn!!!!!!!!!!! I don't get why the graph is B for last one?

[tkjnz]

what did you guys get for the spring question, with the total energy lost

I got 4J, it should have been 0 I think, but I couldnt show the working out to prove it.

i got 4J too, i was going to go back to recheck it but ran out of time

[Greggler]

yeah me too. motion took me like 40 minutes. then took me 20 minutes to do the rest lol and spent 25 minutes pretty much redoing motion.
spring q was a bit of a lolwut moment.

what about the projectile one./ did everyone get around 63m the 63m/s or something like that. i wasnt too sure about that one

[sasha]

i did C for the last graph, inelastic > V drops, energy goes into heat/sound etc
