The football has a mass of 450 g and radii of gyration about its axis of symmetry (z axis) and its transverse axes (x or y axis) of kz = 30 mm and kx = ky = 50 mm, respectively. If the football has an angular momentum of HG = 0.02 kg • m2/s, determine its precession ϕ and spin ψ. Also, find the angle β that the angular velocity vector makes with the z axis.
