1. The problem statement, all variables and given/known data
A blue convertible of mass 1500kg is traveling south, and a red sport utility vehicle of mass 2100kg is traveling west. The total momentum of the system consisting of the two cars is 7500kg*m/s directed at an angle 65.0 west of south.

Split the total momentum vector into the sum of a component pointed south and a component pointed west. That gives you the momentum of each car. Now find the appropriate velocities.
