The whole system has a mass m and is kept on a frictionless horizontal table (figure). 2R - 2R ונ R3R пъ wo blocks A and B. each of mass m, are placed on the two sides of the stand. At = 0, the separation between A and the mirrors is 2R and also the separation between B and the mirrors is 2 R. The block B moves towards the mirror at a speed V. All collisions which take place are elastic.
