A 0.620 kg wood block is firmly attached to a spring (k = 180 N/m). It is noted that the block-spring system, when compressed 0.050 m and released, stretches out 0.023 m beyond the equilibrium position before stopping and turning back. what is the coefficient of kinetic friction between the block and the table?

2. Relevant equations

-(Wnc) = PEf - PEo + KEf - KEo

3. The attempt at a solution

1/2 kx^{2}= 1/2 mv^{2}+ umgd

This equation has two unknowns (u and v). I don't know any other equation to solve for the unknowns, so I'm stuck here... What other equation do I use?
