Astring under a tension of 56.9 n is used to whirl a rock in a horizontal circle of radius 2.55 m at a speed of 19.5 m/s. the string is pulled in and the speed of the rock increases. when the string is 1.18 m long and the speed of the rock is 52.5 m/s, the string breaks. what is the breaking strength (in newtons) of the string?
