Multiple-Concept Example 7 explores the approach taken in problems such as this one. The blades of a ceiling fan have aradius of 0.357 m and are rotating about a fixed axis with an angular velocity of +1.84 rad/s. When the switch on the fan is turned to a higher speed, the blades acquire an angular acceleration of +2.42 rad/s. After 0.555 s have elapsed since the switch was reset, what is (a) the total acceleration (in m/s) of a point on the tip of a blade and (b) the angle o between the total acceleration a and the centripetal acceleration a (See Figure b)?
