At the instant = 30, the frame of the crane is rotating with an angular velocity

At the instant θ = 30°, the frame of the crane is rotating with
an angular velocity of ω₁ = 1.5 rad/s and angular
acceleration of ω̇₁ = 0.5 rad/s², while the boom AB rotates
with an angular velocity of ω̇₂ = 0.5 rad/s and angular
acceleration of ω₂ = 0.25 rad/s². Determine the velocity and
acceleration of point B at this instant.
