In the figure(fegure 1) a $13\mathrm{kg}$ block b held at rest againnt a speing with a focke constant $k=730\mathrm{N}/\mathrm{m}$ inisally, the spring is compressed a dstance $d$. When the tlock is reloased, $\pi$ slides acioss a surlace that is fricticniess except for a rough patch of width $5.0\mathrm{cm}$ that has a coefficient of kinetic friction $1\mathrm{A}=0.43$ Find $d$ such that the block's spoed after crossing the rough patch is $23\mathrm{m}/\mathrm{s}$ Express your answer using two significant figures.
