Solution of the D2 version 02 Dievskaya VA Malyshev IA

Solution of the A2 B2. Rotates with angular velocity w0 = 2,5 rad / s, the rotor of the motor starts to decelerate the forces of aerodynamic resistance, the moment where M1 = 15w, and frictional forces in the bearings, which are currently M2 = 30 Nm. The moment of inertia about the rotational axis J is = 100 kgm2. Determine how long the rotor stops.

Additional information:

Right after the payment you receive a link to the archive with the solution of the problem in theoretical mechanics A2 B1 (condition 1) in the test book "theoretical mechanics" Dievskaya VA Malyshev IA 2009 for university students.
The decision is decorated in a format word (typed or hand-written decision in a Word), packed to the archive zip (open on any PC).

After checking the solutions I would be very grateful if you leave your positive feedback.
