A billiard ball of mass 150 g and radius 2.20 cm starts with a translational speed of 1.00 m/s at point A on the track as shown in the figure below. When the ball reaches points Bits height has decreased by 10 cm. Model the billiard ball as a solid sphere and assume it rolls without slipping on the track. A 5110 cm R 1) What is the angular speed of the billiard ball when it is at point A? (Express your answer to two significant figures.) 2) What is the translational speed of the ball when it is at point B? (Express your answer to two significant figures.) 3) 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? (Express your answer to two significant figures.)
