1. pi/6, 5pi/6, 3pi/2
2. T = 3 and 5/9 s
3. P = 96000, R = 10800
4. 30i,-16j (34ms^-1)
5. 0.04m, 1.87ms^-1
6. 120m ish, doesn't land in Lake
7. 12000ishN,v=12.91ms^-1
8. Can't remember numbers but 113 degrees

troubadour.

Is there any chance I'm going to get method marks if I got wrong answers? This exam... Well, this and C3 have successfully nailed shut the coffin of my physics career. :frown:

I had everything the same as you bar Q5
I had the velocity as sqrt(3.053) or something which came to 1.89ms^-1

People seemed to have what you had, so probably right

Idk why I keep getting it

I remember having something like that for the velocity. definitely 1.8 something

I got the same I think, except number 2. I think I had 2 and 14/9 or something, so must have made a mistake somewhere

Oh **** I forgot the elastic potential energy, it was still extended at 0.45m

Answer is 1.87

Ah man unlucky :/
Though everything else seems right that's a comfortable 95%+

Yeah, and obviously that question. Forgot to mention that. I don't know where I went wrong on Q2 though.

My projectile was wrong, I subbed in something wrong, so I got the right time but wrong distance so will lose that mark

And I'll lose very last mark

And I also didn't find speed in q 4,i left it as velocity vector

Hopefully that's an a* still

Answer is 1.87

I got 2.something i remember :/
The way i did was:
1470(0.04+0.12)^/2(0.40)=0.5x15v^+3g(0.54-0.45)

Yeah, we both forgot to add in the extra

(1470/0.8)(0.05)²

AHHHHHHH! I see, Hmmm one hell of a sneaky question.

I think I just went into robot mode, because it's always above natural length or at natural length, with no epe

Has anyone got a copy of the questions? I've forgotten!

Yeah, you'll be fine

The only one I wasn't entirely sure about was the car on the track. No tendency to sideslip -> Fr = 0, right?

I got the speed to be about 12.6 or something like that. Anyone else?
