Write an expression for the velocity of the system after the collision.

I just need help writing the expression in Part A. If you look at the submission history, you can see the answers I have already attempted.

NOV) (6%) Problem 12: A car with mass me = 1099 kg is traveling west through an intersection at a magnitude of velocity of v. = 5.5 m/s when a truck of mass m = 1901 kg traveling south at v1 = 8.4 m/s fails to yield and collides with the car. The vehicles become stuck together and slide on the asphalt, which has a coefficient of friction of uk = 0.5.
