Does anyone remember what they did for the pan question?
for part a) I used T- particle x g = particles x a
I forgot what i got as an answer though:\
basically I used the values for the whole system instead of just one particle.Is that right???


20.6
15.5

And yh, you're supposed to use the whole system in the first part
did anyone get 1.6m and 66kg for the moments question? I was almost 100% sure that was right
I got the first part for the number 8 wrong (tension), but if my method for the second part and bearing were right, would I still get follow through marks?

Guys for the graph was it like this (look at image): http://www.mediafire.com/convkey/054e/4ztgbchzc7gqw4wzg.jpg

And for the Impulse was it a whole number like 3?

I had 20 min extra and still could not do that stupid force & vectors question.

I got 2.5 to 1 d.p for the Impulse question.


Got 3 exactly

No I got 42 for M and 1.2 for d
For the velocity-time graph question, was T = 8.75? I know I set up the simultaneous equations correctly but I think I may have accidentally divided by 2 instead of multiplying while solving...

Can you compare yours to the pic I posted


Looks right

I got that and tested it and it worked, its correct
Why did I get 0.2Ns for the impulse question??? Did anyone else?
can someone show the working out for the impulse question.. how did you'll get 3 Ns??

I got 1.2m for the distance and 42kg for the mass, so....

Yeah i got 3 also
