he crane boom OA rotates about the z axis with a constant angular velocity of v1 = 0.15
Chapter 20, Problem 20-22(choose chapter or problem)
The crane boom OA rotates about the z axis with a constant angular velocity of \(\omega_{1} = 0.15 \ rad/s\), while it is rotating downward with a constant angular velocity of \(\omega_{2} = 0.2 \ rad/s\). Determine the velocity and acceleration of point A located at the end of the boom at the instant shown.
