Ball I moves with a speed of 1.3m/s at 45°. Ball 2 moves with a speed of [4.2i+3.5j]m/s. They collide and Ball 2 moves away with a speed of 3.2 m/s at 0'2-40°. They both have a mass of 2.1kg. Friction between the balls and the ground is negligible. a) What is the impulse that Ball 1 exerts on Ball 2? [12.3 Ns at 252"] b) If the balls are in contact for 1.0x10's, what is the average net force that Ball 1 exerts on Ball 2? [1230N at 252"] c) What is the average net force that Ball 2 exerts on Ball 1? [1230N at 72"] d) What is the impulse that Ball 2 exerts on Ball 1? [12.3Ns at 72"] e) What is the change in momentum of Ball 1 and what is the change in momentum of Ball 2? (Ball 1: 12.3 Ns at 72' Ball 2: 12.3 Ns at 252"] Before After Ball I moves with a speed of 1.3m/s at 45°. Ball 2 moves with a speed of [4.2i+3.5j]m/s.
