# Three blocks A, B and C are lying on a smooth horizontal surface, as shown in the figure.  A and B have equal masses, m while C has mass M. Block A is given an brutal speed v towards B due to which it collides with B perfectly inelastically.   The combined mass collides with C, also perfectly in elasticity   of the initial kinetic energy is lost in whole process.  What is value of M/m?
