A rotating fan completes 1100 revolutions every minute. consider a point on the tip of a blade, at a radius of 0.18 m. through what distance does the point move in one revolution?
We don't need the angular speed to solve this exercise. In fact, the distance covered by the point in one revolution corresponds to one circumference of radius r, with r being the radius at which the point is located. Therefore, the distance covered by the point in one revolution is [tex]d=2 \pi r = 2 \pi (0.18 m)=1.13 m[/tex]
