Physics Spring Equilibrium Problem?

Posted on 2017-04-26 18:26:00 in Physics by STEPHEN

A 5.64kg block free to move on a horizontal, frictionless surface is attached to one end of a light horizontal spring. The other end of the spring is fixed. The spring is compressed 0.142m from equilibrium and is then released. The speed of the block is 1.34m/s when it passes the equilibrium position of the spring. The same experiment is now repeated with the frictionless surface replaced by a surface for which μk = 0.295. Determine the speed of the block at the equilibrium position of the spring.
