Conservation Linear Momentum w/ 2D collision

A Chevrolet (mC = 1800 kg) and a Ford (mF = 1500 kg) approach an intersection as shown below. The Chevrolet is initially traveling at 12.0 m/s due East. The Ford is initially traveling at 10.0 m/s due North. After the inelastic collision, the Chevrolet has a final velocity of 8.50 m/s at 51.00 North of East. Determine the final velocity of the Ford after the collision in Polar notation. That is, the angle should be measured relative to the positive-x axis.
