In a game of hammer throw, an athlete whirls the ball with a constant speed in a horizontal circle of radius 2. The ball, weighing 50N, is attached to a metal chain. Draw the normal and tangential acceleration of the ball. Also label the weight and other force components. Answer the ff questions by yes or no and explain why:  1)Is the sum of the vertical component of forces acting on the ball zero?  2)Is the normal component of the acceleration of the ball zero? 3.)Is the tangential component of the acceleration of the ball zero? 4.)Is the tension exerted by the chain on the ball the only horizontal force acting on the ball at any instant along its motion?
