Solution of the D2 version 26 Dievskaya VA Malyshev IA

Solution of the D2 B26. For braking the motor rotor is applied thereto resistance moment, depending on the angular velocity M = 0,002w3. The moment of inertia about the rotational axis J is = 0.1 kgm2. Determine the number of revolutions of the rotor after the start of braking and before the time when its angular speed is halved if w0 = 0.5 rad / s.
