A small block of mass m is kept at the left end of a larger block of mass M and length L which is on a horizontal surface such that the system can slide.The system is started towards right with an initial velocity v.The friction coefficient between the surface and the larger block is x and the friction coefficient between the blocks is x/2.Find the time elapsed before the smaller block separates from the bigger block.

I think something is wrong in the question either the small block should be at the upper right corner of the bigger block or the system should be imparted velocity in the left direction.If your question is correct then the length of the small block should be given
