An electric ceiling fan is rotating about a fixed axis with an initial angular velocity magnitude of 0.240 rev/s. The magnitude of the angular acceleration is 0.907 rev/s2rev/s2 . Both the angular velocity and angular acceleration are directed clockwise. The electric ceiling fan blades form a circle of diameter 0.740 m.
Part A: Compute the fan's angular velocity magnitude after time 0.209 ss has passed.
Part B: Through how many revolutions has the blade turned in the time interval 0.209 ss from Part A?
Part C: What is the tangential speed vt of a point on the tip of the blade at time t= 0.209 s?
Part D: What is the magnitude a of the acceleration of a point on the tip of the blade at time t= 0.209 s?
