After typing in your answer, click anywhere outside the box to see what you have typed exactly. Do NOT press the space bar. The cable is pulled at a constant rate 4 ft/s, and the rack is moving at a constant velocity with a magnitude of 4 ft/s in direction as shown. At the instant shown, determine the magnitude, in rad/s, of the angular velocity of the gear. Express your answer to 4 decimal places. Type your answer in the box below. Leave out the unit any negative sign. After typing in your answer, click anywhere outside the box to see what you have typed exactly. Do NOT press the space bar.

Explanation / Answer

as we know,

absolute velcity=radius*angular velocity

absolute velocity of point B(v=r*w=0
