In the figure, a block slides along a track from one level to a higher level, by moving through an intermediate valley. The track is frictionless untill the block reaches the higher level. There a frictional force stops the block in a distance d. The block's initial speed v_0 is 6  m / s, the height difference h is 1.1 m and the coefficient of kinetic friction μ is 0.6. The value of d is
