the direction remains the same, and v can be found by conserving momentum:
10(8) + 6(4) = (10+8)v
Two objects, with masses 10kg and 6kg respectively, move in the same direction in the same straight line at velocities 8m/s and 4m/s repectively, when they collide. The objects remain in contact with each other after collision. Calculate the common velocity and the direction in which they move after the collision.
