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.(sir,please show the steps in details)

Dear student,

In the block systems problems, first draw the FBD of all the blocks separately and find the net forces on each block. Calculate their accelerations and find the time elapsed by the small block to cover the distance L.

Thanks
