20-41. At a given instant the boom AB of the tower crane
rotates about the z axis with the motion shown. At this same
instant, 0 = 60° and the boom is rotating downward such
that = 0.4 rad/s and = 0.6 rad/s². Determine the velocity
and acceleration of the end of the boom A at this instant.
The boom has a length of LAB = 40 m.
