Two cars, both of mass m, collide and stick together. Prior to the collision, one car had been traveling north at speed 2v, while the second was traveling at speed v at an angle ? south of east (as indicated in the figure). After the collision, the two-car system travels at speed vfinal at an angle ? east of north.
