Two blocks of mass m are brought close to each other with a spring (mass negligible) compressed between then. The spring has potential energy 1/2kx2, where k and x are the force constant and the compression of the spring. The system is held together by a string (mass negligible) that opposes the outward force of the spring. When the string is cut, the spring expands to to its natural length (where it stores no more potential energy), and the two blocks fly apart with total kinetic energy equal to the potential energy that had been stored in the spring. In terms of the mentioned quantities, find the mass of the system before the string was cut.
