I couldn't do the last mechanics question. Assumed that the velocity of Q is negative then tried using law of restitution & conservation of momentum, but then couldn't cancel out the velocities in the inequality.

You are right also. as 2 root 2 = 4/(root(2))

What did you get for the range of values of k for which there is a second collision?
This is from FM1

I did stats and mechanics. Stats was pretty easy IMO, mechanics wasn’t too bad either.

I got k>1/e, v=10, can’t remember much else.

Yeah same. That was such a satisfying question and papers were fairly easy

e was 7/18
v was 10 (power question)
v was 9.4 2 sf (parcel down a slope)
messed up last question about k, I formed my equation and got to the part where it was less zero so hopefully I don’t lose too many marks
