Blocks of masses m , 2m , 4m and 8m are arranged in a line on a frictionless floor . Another block of mass m , moving with speed v along the same line (see figure ) collides with mass m in perfectly inelastic manner. All the subsequent collisions are also perfectly inelastic. By the time the last block of mass 8 m starts moving the total energy loss is p% of the original energy . Value of 'p' is close to :
