Physics

An electric ceiling fan is rotating about a fixed axis with aninitial angular velocity magnitude of 0.280 rev/s . The magnitudeof the angular acceleration is 0.895 rev/s2 . Both the the angularvelocity and angular accleration are directed counterclockwise. Theelectric ceiling fan blades form a circle of diameter 0.800 m .

A) compute the fan's angular velocity magnitude after time 0.202s has passed.

B)Through how many revolutions has the blade turned in the timeinterval 0.202 s from Part A?

C)What is the tangential speed vt of a point on the tip of theblade at time t = 0.202 s ?

D) Calculate the magnitude at of the tangential acceleration ofa point on the tip of the blade at time t= 0.202 s .

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