Three identical uniform blocks of mass ’m ’ each and length x ’ are placed on a smooth fixed horizontal surface as shown. There is friction between A and b while there is no friction between and. At the instant shown , the blockhas horizontal velocity of magnitude towards right where as speed of and is zero. At the instant block has covered a distance relative to block, velocity of all blocks are same.
