1. The problem statement, all variables and given/known data A 3.00-kg particle has a velocity of (3.00i-4.00j)m/s. (a)Find its x and y components of momentum. (b) Find the magnitude and direction of its momentum. 2. Relevant equations p=mv 3. The attempt at a solution For part a, I found that the x and y components of momentum is (9.00i-12.00j)kg*m/s. But I am having trouble with the magnitude and direction. I was told to pythag it, but I am still not clear on what to do. Thank you.
