A billiard ball of mass 180 g and radius 2.80 cm starts with a translational speed of 1.00 m/s at point A on the track as shown in the figure below. If point B is at the top of a hill that has a radius of curvature of 65 cm, what is the normal force acting on the ball at point B? Assume the billiard ball rolls without slipping on the track. 1)What is the normal force acting on the ball at point B? (Express your answer to two significant figures.)
