Homework Statement
As in the attachement, find the minimum v such that the ball does not touch the rock.
The Attempt at a Solution
The solution given is mg*cos(theta) - mv^2/R = n < 0, where theta is the angle between the ball and the person.
My question is why is there a normal force acting on the ball? Since the ball is falling downwards without hitting the rock, wouldn't there be no forces acting on it other than centripetal acceleration?
