please help me understand this question. thank you

A horizontal spring of spring constant k and negligible mass is compressed through a distance y from its equilibrium length. An object of mass m that moves on a frictional surface with coefficient of friction & is placed at the end of the spring. The spring is released and returns to its equilibrium length, and the object travels at velocity v. object object equilibrium length What is the coefficient of friction equivalent to? A. 2g 2gm kyz B. 2g Ky C. Zgy KY D. 24y 2gm
