52. The gravitational force acts at the center of mass and cannot provide a torque to change the bola’s angular momentum during the flight. So, the angular momentum before and after the configuration change must be equal. We treat both configurations as a rigid object rotating around a fixed point. The initial and final rotational inertias are 22 2 2 222 2 (2 ) (0) 8 3. i f I mmmm I mmm m =++ = =++= AA A AAA A (a) Since angular momentum is conserved,
