Chapter 6, Problem 39AP
A string under a tension of 50.0 N is used to whirl a rock in a horizontal circle of radius 2.50 m at a speed of 20.4 m/s on a fricitonless surface as shown in Figure P6.25. As the string is pulled in, the speed of the rock increases. When the string on the table is 1.00 m long and the speed of the rock is 51.0 m/s, the string breaks. What is the breaking strength, in newtons, of the string?

A string under tension of 50.0 N is used to whirl a rock in a horizontal circle of radius 2.5 m at a speed of 20.4 m/s on a frictionless table. The string passes through a small hole in the table at the center of this circle. As the string is pulled in, the speed of the rock increases. When the string is 1.00 m long and the speed is 51.0 m/s, the string breaks. What is the breaking strength, in Newtons, of the string?
A certain string just breaks when it is under 25N of tension. A boy uses this string to whirl a 2kg stone in a horizontal circle of radius
3m. The boy continuously increases the speed of the stone. At approximately, what speed will the string break?
A
6 m/s
9 m/s
(c) 12 m/s
D
15 m/s
The mass of the ball is 0.10 kg and the string is 45 cm long. If the tension in the string when the ball is at the top of the circle is 5.75 N, what is the speed of the rock at that location?
