Question 1

Multiple Choice

A gyroscope has a moment of inertia of 0.14 A gyroscope has a moment of inertia of 0.14 and an initial angular speed of 30 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? A) 3.3 * 10<sup>-</sup><sup>2</sup> N M B) 8.1 *10<sup>-</sup><sup>2</sup> N M C) 14 * 10<sup>-</sup><sup>2</sup> N M D) 7.0 * 10<sup>-</sup><sup>2 </sup>N M and an initial angular speed of 30 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?
