A top spins at 25.0 rev/s about an axis that makes an angle 36.0o with the vertical. The mass of the top is 0.5 kg, its rotational inertia about its central axis 4.0×10-4 kg*m2, and its center of mass is 6.0 cm from the pivot point. If the spin is in the counterclockwise from an overhead view, what is the (a) precession rate? ( compute in rev/s but DO NOT enter units)
