A block of mass 0.18 kg is attached to a spring of force-constant $2 \mathrm{~N} / \mathrm{m}$. The coefficient of friction between the block and the floor is 0.1 . Initially the block is at rest and the spring is un-stretched. An impulse is given to the block as shown in the figure. The block slides a distance of 0.06 m and comes to rest for the first time. The initial velocity of the block in $\mathrm{m} / \mathrm{s}$ is $\mathrm{V}=\mathrm{N} / 10$. Then N is
