Collar A moves to the right along the top rail with a constant speed v_A. Find the angular velocity vector Ohm_AB of the link and the velocity v_B of collar B. Work this problem out by hand to the point where you can write an equation of the form M [theta v_B] = (where f_1 or f_2 could be a constant), use symbolic Matlab to solve for theta and V_b, then construct the requested vectors
