A propeller blade can be modeled as a thin uniform bar 3 m long and mass 30 kg. The blade rotates on an axle that is perpendicular to it and through its center. Friction in the axle and air resistance combine to produce a torque of 25 Nm. If the blade is initially turning at 600 rpm, how long before the blades come to a rest? (answer in units of seconds)
