Re: Wow, fuck that

The paper was definitely challenging. Questions five was the worst for me whereas question six and seven were surprisingly easier. Wish I had more time though.

Re: Wow, fuck that

It was 4 or 8 as the distance. I think I did 4 though.

You were supposed to get a negative time???? I got the negative time and tried to figure out what was wrong but couldn't see anything so i just left it.

Did you still subtract it from 10am

Re: Wow, fuck that

the period was pi/2n

they wanted distance travelled in 2pi / n seconds or something, but 2pi/n = 4 periods, therefore, it would have travelled 4 x the amplitude, amplide was 2, therefore distance travelled was 8

Why only 3 projectile motion marks!!!!!!!@@@@

Re: Wow, fuck that

.. isn't it under a velocity-time graph?

Yes. Area under accel graph is velocity, area under velocity graph is displacement.

Me too. Oh geez. So much for an e4 for me

Re: Wow, fuck that

what did you guys get for p? i got some ugly fraction

Fml I didn't study SMH a single bit..I thought projectile motion will be more than SMH.

Something like that.

0.36 ish

Re: Wow, fuck that

I think I got something root 17

Re: Wow, fuck that

im pretty sure its 4 because if u sub the time in the velocity it would give 2. but at t= 2pi / n x=0 therefore its 0-2-0= travels 4 units. IDKKKKKKK

0.36 ish

okay dokey

Re: Wow, fuck that

solving the quadratic, i took it as a decimal and got 0.358 or something ? sound familiar? :\
2 values, 1 was outside the domain of p though, ^ was the other and it was inthe domain

edit someone beat me!

Did you get something under root 17?

yes this was it. it was 7/8 - sqrt17 / 8 which worked out to 0.36

it was like 7-root(17) all over 8 or sumfin like that
