A frictionless disc of mass 0 50 kg is moving in a straight line across an air table at a speed of 2 4 m s when it bumps into an elastic band stretched between two fixed posts If the elastic band exerts an average opposing force of 1 4 N on the disc for 1 5 s what will be the final velocity of the disc 1 8 m s in a direction opposite to the initial velocity
