a block of mass m slides along ahrizontal table with speed v. At s = 0, it hits a spring with spting constat k and begins to experience a frictin oforce. the coefficient of frictio is u, find the distance the spring compresses when it momentairly comes to rest.

## Homework Equations

## The Attempt at a Solution

i belive the frictin part is umgs, is this correct

.5mv

^{2}= .5ks

^{2}+ ugms

if this is correct, how do i get the s alone
