Three indentical uniform blocks of mass ...

Three indentical uniform blocks of mass m each and length L are placed on a smooth fixed horizontal surface as shown. There is friction between A and B (Friction cofficient `mu`) while there is no friction between A and C. At the instant shown, that is at t=0, the block A has horizontal velocity of magnitude u towards right, whereas speed of B and C is zero. At the instant block A has covered a distance L relative to block B velcity of all blocks are same.

The magnitude of total work done by friction on system of three blocks is

Two identical blocks A and B of mass M each are kept on each other on a smooth horizontal plane. There exists friction between A and B. A bullet of mass m hits the the lower block with a horizontal velocity v and goes embedded into it. Find the work done by friction between A and B.
