A solid cone of height 180 mm with a circular base of radius 60 mm is supported by a ball and socket at A. The cone is released from the position θ0 = 30? with a rate of spin ψ0 = 300 rad/s, a rate of precession φ0 = 20 rad/s, and a zero rate of notation. Determine

(a) The maximum value of θ in the ensuing motion,

(b) The corresponding values of the rates of spin and precession.
