An electric ceiling fan is rotating about a fixed axis with an initial angular velocity magnitude of 0.260rev/s . The magnitude of the angular acceleration is 0.893 rev/s2 . Both the the angular velocity and angular accleration are directed counterclockwise. The electric ceiling fan blades form a circle of diameter 0.780 mm .

a) Compute the fan's angular velocity magnitude after time 0.208s has passed.

b)Through how many revolutions has the blade turned in the time interval 0.208s from Part A?

c)What is the tangential speedvtvt of a point on the tip of the blade at time tt = 0.208 s ?

d)Calculate the magnitudeatat of the tangential acceleration of a point on the tip of the blade at time tt = 0.208 s .

e) Calculate the magnitudear of the radial (or centripetal) acceleration of the point at the end of the fan blade.
