A ball of mass m = 0.275 kg swings in a vertical circular path on a string L = 0.850 m long as in Fig- ure P6.45. (a) What are the forces acting on the ball at any point on the path? (b) Draw force diagrams for the ball when it is at the bottom L m of the circle and when it is at the Figure P6.45 top. (c) If its speed is 5.20 m/s at the top of the circle, what is the tension in the string there? (d) If the string breaks when its tension exceeds 22.5 N, what is the maximum speed the ball can have at the bottom before that happens?
