A block of mast \( m=2.00 \mathrm{~kg} \) is attached to a spring of force constant \( k=495 \mathrm{~N} / \mathrm{m} \) as shown in the figure below. The block is puiled to a position \( x_{1}=4,45 \mathrm{~cm} \) to the right of equilibrium and released from rest. (a) Find the speed the block has as it passes through equilibrium if the horizontal surface is frictioniess. \( x \) How much energy is stored in the spring when it is at equilibrium? \( \mathrm{m} / \mathrm{s} \) (b) Find the speed the block has as it passes through equilibrium (for the first time) if the coefficient of friction between bloce and surface is \( \mu_{k}=0.350 \). The force of friction causes an increase in the internat energy of the system and a decrease in the total mechanical enerdy. m/s
