Two masses ${\mathrm{m}}_1$ and ${\mathrm{m}}_2$ are connected by an inextensible cord and arranged as shown in the diagram with ${\mathrm{m}}_1$ sliding along on a frictionless surface and ${\mathrm{m}}_2$ hanging from a light frictionless pulley. What would be the mass of the falling mass ${\mathrm{m}}_2$ if both the sliding mass ${\mathrm{m}}_1$ and the tension T in the cord were known?
