A block of mass m is kept over another block of mass M and the system rests on a horizontal surface, (figure). A constant horizontal force F acting on the lower block produces an acceleration 
in the system, the two blocks always move together.
A
Find the coefficient of kinetic friction between the bigger block and the horizontal surface.
B
Find the frictional force acting on the smaller block.
C
Find the work done by the force of friction on the smaller block by the bigger block during a displacement d of the system.
