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