A rough inclined plane BCE of height (25/6)m is kept on a rectangular wooden black ABCD of height 10 m , as shown in the figure. A small block is allowed to slide down from the top E of the inclined plane. The coefficient of kinetic friction between the block and the inclined plane is 1/8 and the angle of inclination of the inclined plane is sin^-1 (0.6) . IF the small block finally reaches the ground at a point F, then DF will (Acceleration due to gravity, g=10 ms^-2 )
