As part of a carnival game, a mb=0.628 kg ball is thrown at a stack of 15.3 cm tall, mo=0.423 kg objects and hits with a perfectly horizontal velocity of ????b,i=12.1 m/s. Suppose the ball strikes the topmost object. Immediately after the collision, the ball has a horizontal velocity of ????b,f=5.10 m/s in the same direction, the topmost object has an angular velocity of ????o=2.03 rad/s about its center of mass, and all the remaining objects are undisturbed. If the object's center of mass is located ????=10.7 cm below the point where the ball hits, what is the moment of inertia ????o of the object about its center of mass?
