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 0.882 rev/s2 . Both the the angular velocity and angular acceleration are directed counterclockwise. The electric ceiling fan blades form a circle of diameter 0.770 m.

Compute the fan's angular velocity magnitude after time 0.204 s has passed.

 

Through how many revolutions has the blade turned in the time interval 0.204 s from Part A? 

What is the tangential speed vt of a point on the tip of the blade at time t = 0.204 s?

Calculate the magnitude at of the tangential acceleration of a point on the tip of the blade at time t = 0.204 s .

Calculate the magnitude ar of the radial (or centripetal) acceleration of the point at the end of the fan blade.
