What were the two conserved physical quantities in the inelastic collision (comet or whatever)? I think it was 1 mark, i knew momentum was one, I didn't put kintetic energy because its not conserved in inelastic collisions, so randomly put mass lol. I heard someone say it was momentum and total energy is that right?
Yeah that's correct. Kinetic energy is only conserved in elastic collisions. I don't know why but I ca never seem to remember that difference.
got 6.8 m/s for the speed of the carbon atom after the collision with the hydrogen atom. Seemed a little small to me but the carbon atom is massive in comparison so Im hoping that's right
Yeah i got that too. The collision is perfectly elastic so there's no reason to suggest that momentum is not conserved, and the carbon is 11 times bigger than the hydrogen. I think we got this right.

i dont think so because the 420 m/s would have been negative so you should have got an answer in the 70s
