A truck with a mass of 1710 kg and moving with a speed of 14.0 m/s rear-ends a 613 kg car stopped at an intersection. The collision is approximately elastic since the car is in neutral, the brakes are off, the metal bumpers line up well and do not get damaged. Find the speed of both vehicles after the collision in meters per second. m/s truck m/s car As shown in the figure below, object m, = 1.50 kg starts...
