Multiple-Concept Example 7 explores the approach taken in problemssuch as this one. The blades of a ceiling fan have a radius of0.370 m and are rotating about a fixed axis with an angularvelocity of +1.82 rad/s. When the switch on the fan is turned to ahigher speed, the blades acquire an angular acceleration of +2.25rad/s2. After 0.473 s have elapsed since the switch was reset, whatis (a) the total acceleration (in m/s2) of a point on the tip of ablade and (b) the angle between the total acceleration and thecentripetal acceleration?
