. A ventilation fan has blades 0.25 m long rotating at 20 rpm (revolutions per minute). What is the centripetal acceleration of a point on the outer tip of a blade

The centripetal acceleration of a point on the outer tip of a blade is 1.097 m/s²

Explanation:

Given;

length of the fan blade, r = 0.25 m

angular speed = 20 rpm

The angular speed in rad/s is given as;

The centripetal acceleration of a point on the outer tip of a blade is given as;

Therefore, the centripetal acceleration of a point on the outer tip of a blade is 1.097 m/s²
