D2-01 Dievskiy

The fan rotating with an angular velocity ω0 = 3 rad / s, is braked by forces of resistance, whose moment M = 25ω2. The moment of inertia of the fan relative to the axis of rotation is J = 40 kg. M2. Determine, during what time the angular velocity of the fan will be reduced by half.
