At the instant θ = 60°, the construction lift is rotating about the z axis with an angular velocity of ω₁ = 0.5 rad/s, and an angular acceleration of ω̇₁ = 0.25 rad/s² while the telescopic boom AB rotates about the pin at A with an angular velocity of ω₂ = 0.25 rad/s and angular
acceleration of ω̇₂ = 0.1 rad/s². Simultaneously, the boom is extending with a velocity of 1.5 ft/s, and it has an acceleration of 0.5 ft/s², both measured relative to the frame. Determine the velocity and acceleration of point B located at the end of the boom at this instant.
