In the figure a and b AC, DG and GF ar fixed inclined planes BC=EF=x and AB=DE=y. A small block of mass m is released from the point A. It slides down AC and reaches C with speed V_(C). The same block is released from rest from the point D, It slides down DGF and reaches the point F with speed V_(F), Coefficient of kinetic frictions between the block and bot the surfaces AC and DGF are mu. The values of V_(C) and V_(F) is sqrt(kgy-mugx) then find the value of k.

1.	In the figure a and b AC, DG and GF ar fixed inclined planes BC=EF=x and AB=DE=y. A small block of mass m is released from the point A. It slides down AC and reaches C with speed V_(C). The same block is released from rest from the point D, It slides down DGF and reaches the point F with speed V_(F), Coefficient of kinetic frictions between the block and bot the surfaces AC and DGF are mu. The values of V_(C) and V_(F) is sqrt(kgy-mugx) then find the value of k.
