KillGorack / Physics 2010 / 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 following physics responses are provided by a student and, as such, should be considered in that context. While every effort is made for accuracy, absolute correctness cannot be fully guaranteed.
