The frictional moment acting on a rotating turbine disk and its shaft is given by Mf = kω2 where ωis the angular velocity of the turbine and the constant k is 0.038 kg·m2. If the source of power is cut off while the turbine is running with an angular velocity ω0 = 39 rad/s, determine the time t for the speed of the turbine to drop to 0.47ω0. The moment of inertia of the turbine disk and shaft is I = 25 kg·m2.
