The panel assembly and attached x-y-z axes rotate with a constant angular velocity Ω = 0.6 rad/sec about the vertical z-axis. Simultaneously, the panels rotate about the y-axis as shown with a constant rate ω₀ = 2 rad/sec. Determine the angular acceleration α of panel A and find the acceleration of point P for the instant when β = 90°.
