Object A travels in the +x-direction before hitting a stationary object B. Afterwards, object A’s x-momentum is 5.7 × 104 kilogram meters/second and its y-momentum is 6.2 × 104 kilogram meters/second. What is the object’s resultant angle of motion with the +x-axis after the collision?

The momentum vector is (x mom, y mom) and so the angle is 
arc tan ((y mom / x mom).
