The radar antenna shown below is communicating with a satellite. The reference frame attached to the ground is I. The shaft (reference frame S) of the radar antenna spins about KI such that the unit vector IS and JS make an angle of ψ with respect to II and JI respectively. Similarly, the antenna's dish (reference frame D) spins about IS such that the unit vector JD and KD make an angle of ϕ with respect to JS and KS respectively. Determine a general formula for the angular acceleration of the radar dish with respect to the ground. Express your final answer in the satellite-dish reference frame S as shown below.
