D2-26 Dievskiy

To inhibit the rotor of the electric motor, a moment of resistance forces is applied to it, depending on the angular velocity: M = 0.002ω3. The moment of inertia of the rotor relative to the axis of rotation is J = 0.1 kg m2. Determine the number of revolutions of the rotor from the moment of the onset of deceleration to the moment when its angular velocity is halved, if ω0 = 0.5 rad / s.
