An electric celling fan is rotating about a fixed axis with an initial angular velocity magnitude of \( 0.280 \) rev/s . The magnitude of the angular acceleration is \( 0.901 \mathrm{rev} / \mathrm{s}^{2} \). Both the the angular velocity and angular accleration are directed counterclockwise. The electric ceiling fan blades form a circle of diameter \( 0.750 \mathrm{~m} \). Through how many revolutions has the blade tumed in tho time interval \( 0.193 .5 \) from Part A?
