A uniform disc of mass `m` and radius `R` I rotated about an axis passing through its centre and perpendicular to its plane with an angular velocity `omega_()`. It is placed on a rough horizontal plane with the axis of the disc keeping vertical. Coefficnet of friction between te disc and the surface is `mu`, find
(a). The time when disc stops rotating
(b). The angle rotated by the disc before stopping.
