Thank you!

I am having trouble with part b). I found the answer to part a) is -0.4 and for part b) the mark scheme says that the velocity of the 2nd bag is 1.6m/s but how do I find that out? If someone could perhaps show step-by-step of part b)? Thank you!

Thank you so much!

I saw that the answer was 100 and it worked when I put acceleration as 0. Maybe because as he starts and finishes at rest overall its zero. I don't know how else to do it. Maybe it's nothing to do with the acceleration and it was just a coincidence. But thank you anyway!

I think that once I put a=0 and use v=u+at it works as I get 0=0.01t^2 - t. But why/how does a=0. I just can't get my head round it.
