A 2000-kg car approaches an intersection traveling north (y-direction) at 12.0 m/s. A 2400-kg car approaches the same intersection traveling east (x-direction) at 10.0 m/s. The two cars collide at the intersection and lock together. Ignoring any external forces that act on the cars during the collision, what is the speed of the cars immediately after the collision? At what angle (relative to the x-axis) do the cars travel immediately after the collision? At what angle from the x-axis does...
