May 13 2013 M1 Discussion - International Paper

So, this M1 paper is different to the one in the UK.

To not confuse with that paper, this is a separate thread to discuss solutions and possible grade boundaries.

Hope everyone did well!

Anyone remember their answers?

This is from the other thread from elbridge:

This is what I remember (may not be correct):
Q1) Balls colliding - 14Ns and 1.33 something
Q2) Ropes to attached to ceiling - T = 7.xx N and 8.xx N
Q3) Some pulley stuff - T = 26.1 N
Q4) Something about friction - coefficient = 0.411
Q5) Some balls being thrown - t = 2.xx s and h = 17.7 m
Q6) Vectors - time = 2h?, distance (or was this the speed?) = 8.xx km
Q7) Towbar - 1.02 ms-2, T = 517 N, R = 1750 N
Q8) Moments - x = 0.6 and m = 23.5kg
