20–7. At a given instant, the antenna has an angular motion w = 3 rad/s and o = 2 rad/s² about the z axis. At this same instant 0 = 30°, the angular motion about the x axis is w, = 1.5 rad/s, and o, = 4rad/s?. Determine the velocity and acceleration of the signal horn A at this instant. The distance from 0 to A is d = 3 ft. e = 30°
