Here is the answer for the question – **A gyroscope has a moment of inertia of 0.140 kgm2 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 2.00 102 Nm, then in what time interval will the gyroscope coast from 15.0 rad/s to zero?**. You’ll find the correct answer below

### A gyroscope has a moment of inertia of 0.140 kgm2 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 2.00 102 Nm, then in what time interval will the gyroscope coast from 15.0 rad/s to zero?

**The Correct Answer is**

**105s**

### Reason Explained

105s is correct for A gyroscope has a moment of inertia of 0.140 kgm2 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 2.00 102 Nm, then in what time interval will the gyroscope coast from 15.0 rad/s to zero?
