# A question from Rindler Relativity Textbook

## Main Question or Discussion Point

While solving the problem from Rindler 2nd ed. book, I just stuck on the problem 3.24.

A certain piece of elastic breaks when it is stretched to twice its length. At time t=0, all points of it are accelerated longitudinally with constant proper Acceleration alpha, from rest in the unstretched state. prove that elastic breaks at t=sqrt(3)*c/alpha.
