An electric ceiling fan is rotating about a fixed axis with an initial angular velocity magnitude of 0.270 rev/s . the magnitude of the angular acceleration is 0.899 rev/s2 . both the the angular velocity and angular accleration are directed counterclockwise. the electric ceiling fan blades form a circle of diameter 0.740 m.
a. compute the fan's angular velocity magnitude after time 0.207 s has passed. b. through how many revolutions has the blade turned in the time interval 0.207 s from part a? c. what is the tangential speed vtan(t) of a point on the tip of the blade at time t = 0.207 s? d. what is the magnitude a of the resultant acceleration of a point on the tip of the blade at time t = 0.207 s?
