show complete solution and box the final answer (indicate the letter of the correct answer)

3. The uniform 20 lb bar below is three feet long and has an angular velocity of 3 rad/sec clockwise. Point C is the
center of mass of the bar. The initial velocity of point C at the instant shown is zero. Neglecting interaction with
the air, what is the angular velocity of the bar after its center has dropped 10 feet? Use the acceleration due to
gravity, g = 32.2 ft/sec².
