A thin uniform spherical shell of mass \( M \) and radius \( R \) rolls without slipping on a horizontal surface with angular velocity \( \omega \). The kinetic energy of the upper part of the shell above the horizontal line \( A B \) is \( \frac{p}{q} M R^{2} q^{2} \) where \( p \) and \( q \) are co-prime. The value of \( (p+q) \) is
