An electric fan has blades of length `30 cm` as measured from the axis of rotation. If the fan is rotating at `1200 rpm`, find the acceleration of a point on the tip of a blade.

An electric fan has blades of length 30 cm as measured from the axis of rotation .If the fan is rotating at 1200 r.p.m., then the acceleration of a point on the tip of the blade is ("take" pi^(2)=10)
