There are hundred identical sliders equally spaced on a frictionless track as shown in the figure. Initially all the sliders are at rest. Slider 1 is pushed with velocity v towards slider 2. In a collision the sliders stick together. The final velocity of the set of hundred stucked sliders will be :

Three blocks of masses m , m and M are kept on a frictionless floor as shown in the figure .The leftmost block is given velocity v towards the right . All the collision between the blocks are perfectly inelastic . The loss in kinetic energy after all the collision is 5//6th of initial kinetic energy. The ratio of M//m will be
