A man stands on a Zhukovsky bench and holds a rod in his hands vertically along the axis of the bench. A bench with a person rotates with an angular velocity ω1 = 1 rad/s. At what angular velocity ω2 will the bench with the person rotate if the rod is rotated so that it takes a horizontal position? The total moment of inertia of the person and the bench is J = 6 kg m2. Rod length l = 2.4 m, mass m = 8 kg. Assume that the center of mass of the rod with the person is on the axis of the platform.
