An electric ceiling fan is rotating about a fixed axis with an initial angular velocity magnitude of 0.240 rev/s. the magnitude of the angular acceleration is 0.917 rev/s^2. both the the angular velocity and angular acceleration are directed counterclockwise. the electric ceiling fan blades form a circle of diameter 0.720 m. a) compute the fan's angular velocity magnitude after time 0.203 s has passed. compute the fan's angular velocity magnitude after time 0.203 s has passed. express your answer numerically in revolutions per second. b) what is the tangential speed vt of a point on the tip of the blade at time t = 0.203 s? express your answer numerically in meters per second. c) calculate the magnitude at of the tangential acceleration of a point on the tip of the blade at time t= 0.203 s. express the acceleration numerically in meters per second squared.
