You push a 1.3 kg block against a horizontal spring, compressing the spring by 22 cm. Then you release the block, and the spring sends it sliding across a tabletop. It stops 79 cm from where you released it. The spring constant is 220 N/m. What is the coefficient of kinetic friction between the block and the table?
