Ascientist makes a device to catch baseballs. a long bar of total mass 2.2kg and length 1.2m is fixed at its center. it catches a ball of mass 0.15kg moving at v=16m/s in a box at one of its ends. ignore the mass of the catcher box for this problem. what is the angular velocity of the system after the ball is caught?
