An electric ceiling fan is rotating about a fixed axis with an initial angular velocity magnitude of 0.300 rev/s. The magnitude of the angular acceleration is 0.895 rev/s². Both the the angular velocity and angular accleration are directed counterclockwise. The electric ceiling fan blades form a circle of diameter 0.790 m.
What is the tangential speed vr of a point on the tip of the blade at time t = 0.202 s ?
Express your answer numerically in meters per second.
