1. The problem statement, all variables and given/known data I'm stuck on this problem, and I don't really know how to approach it. 2. Relevant equations Pretty much just p=mv And the conservation of linear momentum: total initial mv = total final mv 3. The attempt at a solution I tried just plugging in the variables into the conservation of momentum equation, but it doesn't work out. I know you can't just add velocity vectors that are in different directions, right? They have to have the same I hat or j hat? How would you solve for them?
