Consider a block-spring system as shown below. The spring has a spring constant of 133 N/m, while the block has a mass of 5.31 kg. The spring is compressed by 0.185 m from its equilibrium position and released from rest, and the block is found to come to a stop right at the equilibrium point. What is the coefficient of kinetic friction between the block and floor surfaces?
