D2-13 Dievskiy

The driving moment of the electric motor is inversely proportional to the square of the angular velocity M = 1.5 / ω2. The moment of inertia of the rotor relative to the axis of rotation is J = 50 kg m2. Determine after what time the angular velocity of the rotor will triple, if the initial angular velocity is ω0 = 0.5 rad / s.
