Question: a gyroscope has a moment of inertia of 0.140?
Answer: A gyroscope has a moment of inertia of 0.140 kg×m2 and has an initial angular speed of 15.0 rad/s. If a lubricant is applied to the bearings of the gyroscope so that frictional torque is reduced to 2.00 ´ 10-2 N×m, then in what time interval will the gyroscope coast from 15.0 rad/s to zero?
