released from rest. (a) Find the speed the block has as it passes through equilibrium if the horizontal surface is frictionless. \[ \mathrm{m} / \mathrm{s} \] (b) Find the speed the block has as it passes through equilibrium (for the first time) if the coefficient of friction between block and surface is \( \mu_{\mathrm{k}}=0.350 \). \[ \mathrm{m} / \mathrm{s} \]
