A light horizontal spring has a spring constant of 107 N/m. A 3.08 kg block is pressed against one end of the spring, compressing the spring 0.107 m. After the block is released, the block moves 0.226 m to the right before coming to rest. The acceleration of gravity is 9.81 m/s 2 . What is the coefficient of kinetic friction between the horizontal surface and the block
