Multiple-Concept Example 7 explores the approach taken in problems such as this one. The blades of a ceiling fan have a radius of 0.375 m and are rotating about a fixed axis with an angular velocity of +1.95 rad/s. When the switch on the fan is turned to a higher speed, the blades acquire an angular acceleration of +2.69 rad/s2. After 0.473 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 (b) the angle between the total acceleration and the centripetal acceleration (See Figure 8.13b)?(adsbygoogle = window.adsbygoogle || []).push({});

I am very lost on this problem.

THe example pretty much just told me that

a = Sqrt ac^2 + aT^2

I have no clue how to begin this problem. please help even if its just a hint.

THanks
