Multiple-Concept Example 7 explores the approach taken in problems such as this one. The blades of a ceiling fan have a radius of 0.380 m and are rotating about a fixed axis with an angular velocity of 11.50 rad/s. When the switch on the fan is turned to a higher speed, the blades acquire an angular acceleration of + 2.00 rad/s2. After 0.500 s has elapsed since the switch was reset, what is (a) The total acceleration (in m/s2) of a point on the tip of a blade (b) The angle Φ between the total acceleration  and the centripetal acceleration C?
