You push a 4.6 kg block against a horizontal spring, compressing the spring by 26 cm. Then you release the block, and the spring sends it sliding across a tabletop. It stops 83 cm from where you released it. The spring constant is 330 N/m. What is the coefficient of kinetic friction between the block and the table?(adsbygoogle = window.adsbygoogle || []).push({});

So to start, I have figured out the potential energy of the spring when it is compressed, and it is .5 (330 N/m)(.26 m) squared = 11.154 J But after that, I am not really sure what to do. I tried something with force x distance, but I cannot remember what I did. But I am just unsure where to start on this one. Help would be great
