A gyroscope has a moment of inertia of 0.140 kg m²and has an initial angular speed of 12.0 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 12.0 rad/s to zero?

Question

A gyroscope has a moment of inertia of 0.140 kg

m²and has an initial angular speed of 12.0 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 A gyroscope has a moment of inertia of 0.140 kg m2 and has an initial angular speed of 12.0 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 12.0 rad/s to zero? A) 150 s B) 105 s C) 90.0 s D) 84.0 s

M, then in what time interval will the gyroscope coast from 12.0 rad/s to zero?
