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 . 1) Compute the fan's angular velocity magnitude after time 0.208 s has passed.
2)Through how many revolutions has the blade turned in the time interval 0.208 s from Question 1?
3)What is the tangential speed vt of a point on the tip of the blade at time t = 0.208 s ?
4)Calculate the magnitude at of the tangential acceleration of a point on the tip of the blade at time t = 0.208 s .
5)Calculate the magnitude ar of the radial (or centripetal) acceleration of the point at the end of the fan blade.
