Small wheels attached to the ends of rod AB roll along two surfaces. Knowing that at the instant shown the velocity vA of wheel A is 4.5 ft/s to the right and the relative velocity vB/A of wheel B with respect to wheel A is perpendicular to rod AB, determine
(a) The relative velocity vB/A,
(b) The velocity vB of wheelB.
