Figure 11.15 shows the dimensions of a 880-g wooden baseball bat whose rotational inertia about its center of mass is 0.048 kg·m 2 . If the bat is swung so its far end moves at 50 m/s, find (a) its angular momentum about the pivot P and (b) the constant torque applied about P to achieve this angular momentum in 0.25 s. ( Hint : Remember the parallel-axis theorem.) FIGURE 11.15 Problem 40
