A string under a tension of 49.5 N is used to whirl a rock in a horizontal circle of radius 2.55 m at a speed of 20.3 m/s on a frictionless surface as shown in the figure below. 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 49.5 m/s, the string breaks. What is the breaking strength, in newtons, of the string?

Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.
