A car of mass m moving at a speed v_1 collides and couples with the back of a truck of mass 2m moving initially in the same direction as the car at a lower speed v_2. (a) What is the speed v_f of the two vehicles immediately after the collision? (b) What is the change in kinetic energy of the car–truck system in the collision?
