Object 1 has a mass m1 and a velocity 1 = (2.78 m/s) in the x direction. Object 2 has a mass m2 and a velocity 2 = (3.21 m/s) in the y direction. The total momentum of these two objects has a magnitude of 16.8 kgm/s and points in a direction 66.5° above the positive x-axis. Find m1 and m2. I tried doing p=mv for each one but it didn't work. I think that it has something to do with the resulting angle, but I don't know how to incorporate that into the equation.
