Here is the answer for the question – **A rotating flywheel can be used as a method to store energy. If it has 1.0 106 J of kinetic energy when rotating at 400 rad/s, and if a frictional torque of 4.0 Nm acts on the system, in what interval of time would the flywheel come to rest?**. You’ll find the correct answer below

### A rotating flywheel can be used as a method to store energy. If it has 1.0 106 J of kinetic energy when rotating at 400 rad/s, and if a frictional torque of 4.0 Nm acts on the system, in what interval of time would the flywheel come to rest?

**The Correct Answer is**

**21 min**

### Reason Explained

21 min is correct for A rotating flywheel can be used as a method to store energy. If it has 1.0 106 J of kinetic energy when rotating at 400 rad/s, and if a frictional torque of 4.0 Nm acts on the system, in what interval of time would the flywheel come to rest?
