14.6.7
The tube rotates about the vertical axis Oz, its moment of inertia Iz = 0,075 kg · m2. On the tube, under the influence of the internal forces of the system, a ball M of mass m = 0.1 kg moves. When the ball is on the Oz axis, the angular velocity ω0 = 4 rad / s. At what distance l is the angular velocity equal to 3 rad / s? (Answer 0.5)
