A top spins at 30rev/s about an axis that makes an angle of 30 deg. with the vertical. The mass of the top is 0.50kg, its rotational inertia about its central axis is 5.0X10^-4 kg m^2, and its center of mass is 4.0 cm from the pivot point. Viewed from overhead, the spin is clockwise.
(A) what is the precession rate?
(B) what is the direction of precession as viewed from overhead?
