A rock of mass m = 0.97 kg is attached to a massless string of length L = 0.71 m. The rock is swung in a vertical circle faster and faster up to a speed of v = 2.4 m/s, at which time the string breaks. What is the magnitude of the tension, in newtons, at which the string breaks?

A 2.0-kg white rock is spinning at the end of a light (massless)
string in a circular path with a radius of 1.25 m on a horizontal
frictionless surface (figure below). The rock has a tangential
speed of the rock was 5.0 m/s. As you can imagine, the string
slowly winds around a vertical rod and several seconds later the
length of the string has shortened to 0.50 m. What is the tangental
