    An electric ceiling fan is rotating about a fixed axis with an initial angular velocity of 0.200 rev/s . The angular acceleration is 0.911 rev/s^2 . Its blades form a circle of diameter 0.720m .

    a) Through how many revolutions has the blade turned in the time interval 0.201s?
    b) What is the tangential speed v_tan (in m/s) of a point on the tip of the blade at time 0.201s?
    c) What is the magnitude of the resultant acceleration (in m/s^2)of a point on the tip of the blade at time 0.201s?
