The earth rotates through one complete revolution every 1,440 minutes. Since the axis of rotation is perpendicular to the equator, you can think of a person standing on the equator as standing on the edge of a disc that is rotating through one complete revolution every 1,440 minutes. Find the angular velocity of a person standing on the equator. ? If the answer needs rounding, round it to five decimal places. ? __________ rad/min
