The load is being lifted upward at a constant rate v relative to the crane boom AB. At the instant shown, the boom is rotating about the vertical axis at a constant rate ω₁, and the trolley T is moving outward along the boom at a constant rate v_t. Furthermore, at this same instant the rectractable arm supporting the load is vertical and is swinging in the y-z plane at an angular rate ω₂, with an increase in the rate of swing α₂. Determine the velocity and acceleration of the center G of the load at this instant.
