PASSAGE

A rigid rod AB of length

L = 2\text{ m}

moves in the plane. End A is constrained to slide along a frictionless horizontal surface, and end B is constrained to slide along a frictionless vertical wall. At the instant shown, end A has velocity

v_A = 3\text{ m/s}

directed horizontally (away from the wall), and the rod makes an angle of

\theta = 30°

with the horizontal.

Using the instantaneous center of zero velocity (IC), what is the angular velocity

\omega

of the rod at this instant, and in which direction does it rotate?
