Answer:
Centripetal acceleration acts on the object along the radius towards the centre of the circular path.
When a point object is moving on a horizontal circular path with a constant speed, the direction of its velocity vector at an instant is changing with time. It means in a uniform circular motion the velocity vector of the object is changing with time. This indicates that the uniform circular motion is an example of accelerated motion.
Here, acceleration of a point at the tip of the blade
= centripetal acceleration
