The spacecraft is revolving about its z-axis, which has a fixed space orientation, at the constant rate p = 1/10 rad/s. Simultaneously, its solar panels are unfolding at the rate β˙ which is programmed to vary with β as shown in the graph. Determine the angular acceleration a of panel A an instant 

(a) Before and an instant 

(b) After it reaches the position β = 18°.
