Solution of the D2 version 01 Dievskaya VA Malyshev IA

Solution of the A2 B1. The fan rotates at an angular velocity w0 = 3 rad / s, is hampered by the resistance moment is M = 25w2. The moment of inertia about the axis of rotation of the fan is equal to J = 40 kgm2. Determine how long the angular velocity of the fan is reduced by half.
