I think I got that too for the velocity question or something. At first, my calculator kept saying maths error because the numbers were too big to square root at the same time, so I had to square root the answer separately.
Yeah, for the velocity i think when v=p/m. But i also remember doing 0.2/0.42 because the momentum was 0.2 and masses together were 0.42?

wasn't the momentum just 0.1? because the M1 was 0.1 and M2 was stationary so it had 0 velocity x 0.21kg so 0 momentum so the overall momentum had to be 0.1? idk heh
