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 paints B its height has decreased by 10 cm. Model the billiard ball as a solid sphere and assuma it rolls without slipping on the track. 1) What is the angular speed of the billiard ball when it is at point A? [Express your answer to two significant figures.) w= rad/s 2) What is the translational speed of the ball when it is at point 7 |Express your answer to two significant figures.) v= mfs Sul [ @ | 3) If point Bis 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 57 (Express your answer to two significant figures.)
