A set of a identical cubical blocks lies at rest parallel to each other along a line on a smooth horizontal surface. The separation between the near surface of any two adjacent blocks is `L`. The block at one and is given a speed `v` towards the next one at time `t = 0`. All collisiona are completely inelastic , then the last block starts moving at
