<p>Multiple-Concept Example 7 explores the approach taken in problems such as this one.&#160; 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 +1.50 rad/s.&#160; When the switch on the fan is turned to a higher speed, the blades acquire an angular acceleration of +2.00 rad/s^2.&#160; After 0.500 s have elapsed since the switch was reset, what is (a) the total acceleration (in m/s^2) of a point on the tip of a blade and (b) the angle&#160; &#966; between the total acceleration and the centripetal acceleration?&#160; ( See Figure 8.12 b.)</p>
