Here is the answer for the question – **A gyroscope has a moment of inertia of 0.14 kgm2 and an initial angular speed of 15 rad/s. Friction in the bearings causes its speed to reduce to zero in 30 s. What is the value of the average frictional torque?**. You’ll find the correct answer below

### A gyroscope has a moment of inertia of 0.14 kgm2 and an initial angular speed of 15 rad/s. Friction in the bearings causes its speed to reduce to zero in 30 s. What is the value of the average frictional torque?

**The Correct Answer is**

**7.0 10^-2 Nm**

### Reason Explained

7.0 10^-2 Nm is correct for A gyroscope has a moment of inertia of 0.14 kgm2 and an initial angular speed of 15 rad/s. Friction in the bearings causes its speed to reduce to zero in 30 s. What is the value of the average frictional torque?
