A ball moves in a vertical circle attached to a light string of length 0.3 m fixed at its center. Assume that the only force acting on the ball are its weight and the tension of the string. Determine the minimum speed the ball must have, when the string makes a 90 degree angle with the vertical, so as to complete the circle by reaching the top.

A child is swinging a 380-g ball at the end of a 69.0-cm-long string in a vertical circle. The string can withstand a tension of 16.0 N before breaking. (a) What is the tension in the string when the ball is at the top of the circle if its speed at that point is 3.90 m/s? (b) What is the maximum speed the ball can have at the bottom of the circle if the string does not break?

A 5.61-kg ball hangs from the top of a vertical pole by a 2.43-m-long string. The ball is struck, causing it to revolve around the pole at a speed of 4.17 m/s in a horizontal circle with the string remaining taut. Calculate the angle, between 0° and 90°, that the string makes with the pole. Take g = 9.81 m/s2. What is the tension of the string?
