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 0.895 rev/s^2 . both the the angular velocity and angular accleration are directed clockwise. the electric ceiling fan blades form a circle of diameter 0.790 m .
1. compute the fan's angular velocity magnitude after time 0.194s has passed. (rev/s)
2. through how many revolutions has the blade turned in the time interval 0.194s from part a? (rev)
3. what is the tangential speed vtan(t) of a point on the tip of the blade at time t = 0.194s ? (m/s)
4. what is the magnitude a of the resultant acceleration of a point on the tip of the blade at time t = 0.194s ? (m/s^2)
