Discover the initial angular velocity in units of rad

Reference no: EM13672642

A wheel with a rotational inertia of 5.0 kg m² is rotating in a horizontal plane at 600 rev/min. A rim brake exerts a torque of 500 Nm on the inside rim of the wheel. Discover the initial angular velocity in units of rad/s and the number of revolutions the wheel rotates during before it comes to rest.
