8. While being thrown, a net force of 132 N acts on a baseball (mass = 140 grams) for a period of 4.5x10 2 %3D seconds. a. What is the magnitude of the change in momentum of the ball? b. If the initial speed of the baseball is 0.0m/s, what will its speed be when it leaves the pitcher's hand? C. When the batter hits the ball, a net force of 1320 N, opposite to the direction of the ball's initial motion, acts on the ball for 9.0x10 s during the hit. What is the final velocity of the ball? d. What force does the ball exert on the bat? Explain
