Thanks for your reply! Oh, for the components, yes I understand what you mean, but the style that my teacher taught us was that he just subtitled each section so in the end as long as we make a vector triangle for the final velocity (sorry, I guess I should've specified components in each of...

I went through with this since I've got no replies :( Anyways, my results ended up to be: v1' = 2.3m/s [W38N] v2' = 2.4m/s [E27N] These numbers don't seem to make sense at all... The heavier ball starts moving faster after collision and is directed more towards East than what it was...

Homework Statement A 1.2kg mass moving 2.4m/s [East] has an elastic collision with a 2.4kg mass moving 1.8m/s [North]. What are the final velocities? ------------------------------------- I know that I need Ek before and after the collision, but I'm not sure how to calculate it for this...
