*20-40. At the instant e = 60°, the construction lift is rotating about the z axis with an angular velocity of w, = 0.5 rad/s and an angular acceleration of ở = 0.25 rad/s? while the telescopic boom AB rotates about the pin at A with an angular velocity of wn = 0.25 rad/s and angular acceleration of on = 0.1 rad/s. 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. 15 ft 2 ft
