    Two cars approach an ice-covered intersection. One car, of mass 1.25 103 kg, is initially traveling north at 11.1 m/s. The other car, of mass 1.58 103 kg, is initially traveling east at 11.1 m/s. The cars reach the intersection at the same instant, collide, and move off coupled together. Find the velocity of the center of mass of the two-car system just after the collision. Please provide magnitude & direction (ex - 30 degrees North of West)

    Two cars of the same mass collide at an intersection. Just before the collision one car is traveling east at 50.0 km/h and the other car is traveling south at 60.0 km/h. If the collision is completely inelastic, so the two cars move as one object after the collision, what is the speed of the cars immediately after the collision? _______ km/h
