Yeah i got 0.6 i think around 0.61 or 0.62 i can't remember exactly! and I found the equation of the line so I did y=-2/3x+6 i think it was that anyway
Yea I think it was something like that. How did you find the 0.6? Did you find W (which was about root 125/8) and Vmax (using momentum) then found a?

What did you get for the last question, the amplitude? Was it 0.6 something?
Also, was the triangle question a lamina or a solid? Please don't say it was a solid.
Yeh 0.6 something amd triangle was lamina.

YES!! I did exactly that, omg this is so good i thought i might have messed that question up but i guess not
4. Guys before you type a question can you put IAL/UK because people are getting confused haha

What did you get for the time? I used the reference circle and got 136 or something divided by 360 * Time period. I can't remember what the Time Period was.
6. Regular, wtf was the answer to the time question, I always get those wrong I got .48 sec?

Yea I think I got something similar. What was the time period? I got 136/360 * time period.

Didn't get an answer of that part I had to leave it as i had earlier parts of the paper to go back and finish and then i ran out of time Oh well hopefully still enough to be able to get an A overall if i do well in FP1
9. 2pi/5 I think

There weren't too many marks for it I think.

yeah I think it was only 3 or 4 so I decided to finish the tension question cut that was worth loads
12. The Tension time question was less then right? Not less then equal to?

Me and my friend both got 0.6something.

Question was a lamina I believe. I got 3cm as the answer.

That exactly what happened to me .____.

Yea it was less than
17. For the tension show that did you say Tcos(30) > mg ?

What did you get for the angle of suspension? was it 18* ?
