Aball of mass m is released at the top edge of a frictionless half-pipe with a radius of curvature r. at the bottom of the pipe, the ball is moving with a speed v. what is the normal force acting on the ball at this point?
Answers: 2
= Normal force acting in upward direction 
 = mass of the ball 
 = weight of the ball acting in downward direction = mg
 = speed of the ball at the bottom 
 = radius of curvature
