The slider C moves at vc m/s down the inclined shaft. Determine the angular velocities of links AB and BC, at the instant shown. Give only numerical answers. The unit vector for angular velocity is included with the units in the form k rad/s; you must enter the correct sign with your numerical answer. Note that link AB is the same length as link BC.
