Question

Multiple-Concept Example 7 explores the approach taken in problems such as this one. The blades of a ceiling fan have a radius of 0.384 m and are rotating about a fixed axis with an angular velocity of +1.49 rad/s. When the switch on the fan is turned to a higher speed, the blades acquire an angular acceleration of +2.43 radfs2. After 0.676 s have elapsed since the switch was reset, what is (a) the total acceleration (in m/s2) of a point on the tip of a blade and CIO the angle 44 between the total acceleration (72 and the centripetal acceleration ac (See Figure 8.13b)?
