An electric ceiling fan is rotating about a fixed axis with an initial angular velocity magnitude of 0.290 . The magnitude of the angular acceleration is 0.888 . Both the the angular velocity and angular accleration are directed clockwise. The electric ceiling fan blades form a circle of diameter 0.800 .

a) Compute the fan's angular velocity magnitude after time 0.199 has passed. Express your answer numerically in revolutions per second. I figured out a and got .467 rev/s and i know thats correct.

b) Through how many revolutions has the blade turned in the time interval 0.199 from Part A? Express the number of revolutions numerically.

c) What is the tangential speed of a point on the tip of the blade at time = 0.199 ? Express your answer numerically in meters per second.

d) What is the magnitude of the resultant acceleration of a point on the tip of the blade at time = 0.199 ? Express the acceleration numerically in meters per second squared.
