For a short interval of motion, collar A moves along its fixed shaft with a velocity v_A = 2 m/s in the Y-direction. Collar B, in turn, slides along its fixed vertical shaft. Link AB is 700 mm in length and can turn within the clevis at A to allow for the angular change between the clevises. For the instant when A passes the position where y = 200 mm, determine the velocity of collar B using nonrotating axes attached to B and find the component ω_n, normal to AB, of the angular velocity of the link. Also solve for v_B by differentiating the appropriate relation x² + y² + z² = l².
