A block of mass $m=2.00 \mathrm{kg}$ is attached to a spring of force constant $k=500 \mathrm{N} / \mathrm{m}$ as shown in Figure $P 7.15 .$ The block is pulled to a position $x_{i}=5.00 \mathrm{cm}$ to the right of equilibrium and released from rest. Find the speed the block has as it passes through equilibrium if $(\mathrm{a})$ the horizontal surface is frictionless and (b) the coefficient of friction between block and surface is $\mu_{k}=0.350$
