Solution 14.6.6 collection of Kep OE 1989

14.6.6. The athlete, jumping from a springboard into water, doing somersaults in the air. At the moment of separation from the springboard he tells himself angular velocity ω0 = 1,5 rad / s around a horizontal axis passing through its center of mass. In this case the moment of inertia about the rotational axis of the athlete I0 = 13,5 kg · m2. Determine the angular velocity of the athlete, when he during a flight, drawing in the hands and feet, reduced to the moment of inertia I = 5,4 kg · m2.
