The next two questions share the same information Base your answers to questions 27 and 28 on the information and diagram below. On a frictionless horizontal surface, two bodies make a head-on collision and stick together. Body 1 has a mass of 3.50 kg and initially moves to the right with speed 7.0 m/s. Body 2 is initially is at rest. A graph of the force exerted onto Body 2 from Body 1 during the collision is shown.
