Light rope ball model, the condition of the ball reaching the highest point, v >;; √gr, the direction of rope elasticity T.
When v=√gr, the elasticity of the rope is T=0N,

When v > √ gr, the direction of the rope elasticity T is towards the center of the circle, and the dynamic equation of the ball Mg+T = MV 2/R.

When v < √ gr, the ball will not reach the highest point and make a curve motion.
