Assume a billiard ball is a solid sphere. Its radius is 3 cm and mass is 500 grams. The coefficient of static friction between the ball and the surface is .70. a) Where should you hit the ball so that it experiences pure rolling motion without the need for any friction force? What is its acceleration if the force is 10 Newtons? b) What is the highest you can hit it with 10 Newtons and still have pure rolling motion? What is the acceleration now? c) What is the lowest you can hit it with 10 N for pure rolling motion? What is it’s a?
