The angular velocity vector of a football which has just been kicked is horizontal, and its axis

Question:

The angular velocity vector of a football which has just been kicked is horizontal, and its axis of symmetry OC is oriented as shown. Knowing that the magnitude of the angular velocity is 200 rpm and that the ratio of the axial and transverse moments of inertia is I/I'= 1/3, determine

(a) The orientation of the axis of precession OA,

(b) The rates of precession and spin.
