An electric ceiling fan is rotating about a fixed axis with an initial angular velocity magnitude of 0.220 rev/s. The magnitude of the angular acceleration is 0.916 rev/s2. Both the angular velocity and angular acceleration are directed counterclockwise. The electric ceiling fan blades form a circle of diameter 0.710 m.

Compute the fan's angular velocity magnitude after time 0.192 ss has passed. (Express your answer numerically in revolutions per second.)

Through how many revolutions has the blade turned in the time interval 0.192 ss from Part A? (Express the number of revolutions numerically.)

What is the tangential speed vt of a point on the tip of the blade at time t = 0.192 s? (Express your answer numerically in meters per second.)

Calculate the magnitude at of the tangential acceleration of a point on the tip of the blade at time t = 0.192 s. (Express the acceleration numerically in meters per second squared.)

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