An electric ceiling fan is rotating about a fixed axis with an initial angular velocity magnitude of 0.220 rev/s . The magnitude of the angular acceleration is 0.920 rev/s2 . Both the the angular velocity and angular acceleration are directed counterclockwise. The electric ceiling fan blades form a circle of diameter 0.800 m

Angular velocity = 0.240 rev/s Angular acceleration = 0.917 rev/s² Diameter = 0.720 m (a). We need to calculate the angular velocity after time 0.203 s Using equation of angular motion Put the value in the equation The angular velocity is 0.426 rev/s. (b). We need to calculate the tangential speed of the blade Using formula of  tangential speed Put the value into the formula The tangential speed of the blade is 0.963 m/s. (c). We need to calculate the magnitude at of the tangential acceleration Using formula of tangential acceleration Put the value into the formula The tangential acceleration is 2.074 m/s². Hence, This is required solution.
