Question

Physics

An electric ceiling fan is rotating about a fixed axis with aninitial angular velocity magnitude of 0.260 rev/s . The magnitudeof the angular acceleration is 0.881 rev/s2 . Both the the angularvelocity and angular accleration are directed clockwise. Theelectric ceiling fan blades form a circle of diameter 0.750 m .

What is the tangential speed vtan(t) of apoint on the tip of the blade at time t = 0.203 s ?

What is the magnitude a of the resultant accelerationof a point on the tip of the blade at time t = 0.203 s?
