The projectile precesses about the Z axis at a constant rate of  = 15 rad/s when it leaves the barrel of a gun. Determine its spin  and the magnitude of its angular momentum HG. The projectile has a mass of 1.5 kg and radii of gyration about its axis of symmetry (z axis) and about its transverse axes (x and y axes) of kz = 65 mm and kx = ky = 125 mm, respectively.
