The top has a mass of 90 g, a center of mass at G, and a radius of gyration k = 18 mm about its axis of symmetry. About any transverse axis acting through point O the radius of gyration is kt = 35 mm. If the top is connected to a ball-and-socket joint at O and the precession is ωp = 0.5 rad/s, determine the spin ωs.
