Was that a Maths exam? (3 Viewers)

[4theHSC]

Kinda bothered me, so much calculations and not much theory,, all that memorising went to waste, meh its over, congrats peoples we made it, most of us finished now

 

[cutemouse]

lol, real Physics is really maths. The old HSC Physics course was like 95% calculations.

i like the electron one, the mix of parallel plates with projectile motion, was a good question, made you think

 

[arjungamer123]

Yeah. If this is an indication for the future, next year's people can expect more calculations. I like it.

 

[Ostentatious]

Me too, maths calculations is what makes physics sexy.

Knowing how to apply the equations is sexier.

I hated that one! lol. Made it all up, just sticking it into equations. Hopefully I might scrape 1/3

I got 5.909 as the time, what did everyone else get

 

[La Bomba]

for electron one i used f=qvbsin0. and subed in a value for B. wont get al marks but wil get part marks. didnt even think of doing a projectile equation. edit jus realised i had to find v in the parallel plates. would of had to use projectile equation. fuck

That seems way too long I got something multiplied by 10^-8.

 

[copeys]

That seems way too long I got something multiplied by 10^-8.

O. M. G.

So did I... I may have got that question right!!! lol

Same here. SWEET. I like the high level of maths in the physics. It makes you think and apply different equations.

me too i think it was like 5.8 times 10^-8 sec

Yeah that was good, but was a 9.8 or was it the force from the previous question?

from previous, used f=ma and u got mass electron on data sheet

 

[Ostentatious]

I mean was the acceleration in the projectile question 9.8?

 

[Phoenix Fury]

That was horrible, so much for only 15% or 25% calculations. Very disappointing.

 

[random-1005]

I mean was the acceleration in the projectile question 9.8?

no

(1.602*10^-16)/(9.109*10^-31)

thats a

then v=u+at
V=0 at max, and times time by 2

 

[Ostentatious]

kthanks

 

[cutemouse]

no

(1.602*10^-16)/(9.109*10^-31)

thats a

then v=u+at
V=0 at max, and times time by 2

Or use S=ut+1/2at^2 and use S=0.

or use t=2usinθ / g and use g as the accel.

 

[carlytse621]

i forgot to times 2......
i am so stupid that i was thinking V will be 0 = ='''''
well...then i got 2/3
