25. 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 a frictionless on surface as shown in Figure P6.25. As the string is pulled in, the speed of the rock increases. When the m R 7 Figure P6.25 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?
