Serway & Jewett — Circular Motion and Other Applications of Newton's Laws: Problem 31
A ball of mass \(m = 0.275 \text{ kg}\) swings in a vertical circular path on a string \(L = 0.850 \text{ m}\) long as in Figure P6.31. (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 of the circle and when it is at the top. (c) If its speed is \(5.20 \text{ m/s}\) at the top of the circle, what is the tension in the string there? (d) If the string breaks when its tension exceeds \(22.5 \text{ N}\), what is the maximum speed the ball can have at the bottom before that happens?
