A block of mass 1kg is at rest on a horizontal surface at x=0.A force of 6N is applied on block toward positive x -axis.Coefficient of friction between block and surface is variable and depends on the its distance x from origin as `mu=((2-x)/(10))`. If `v` is speed of block at x=2. Find `(v^(2))/(1000)`.
