A pitcher throws a fastball with a speed of 45 m/s towards home plate. The batter swings his bat (mbat = 0.94 kg) with a speed of 47 m/s and hits the ball (mball = 0.145 kg) in the opposite direction with a speed of 50 m/s. The time of contact between the bat and the ball is 0.7 milliseconds (0.0007s). 1: What is the change in momentum of the ball in kg*m/? 2: What is the average force in N exerted on the ball by the bat? 3:What is the acceleration of the ball in m/s²?

Problems 44 and 45 are paired. C A model rocket is shot straight up. As it reaches the highest point in its trajectory, it explodes in midair into three pieces with velocities indicated by the arrows in Figure P10.44, as viewed from directly above the explosion. Rank the mass of each piece in order from smallest to largest and justify your answer. FIGURE P10.44 Problems 44 and 45.
