A disc of radius \( R \) and mass \( m \) is projected on to a horizontal floor with a backward spin such
\( \mathrm{P} \) that its centre of mass speed is \( v_{0} \) and angular velocity is \( \omega_{0} \). What must be the minimum value of \( \omega_{0} \) so that the disc eventually returns back?
