A block having a mass of 2.80 kg is given an initial velocity of 1.2m/s when it collides with a spring. The constant force of friction acts between the block and the surface with (mu sub k=0.5) and the force constant of the spring is k=100N/m. What is the maximum compression?(adsbygoogle = window.adsbygoogle || []).push({});

I've been stuck on the problem for a while.

Workfriction + KEi + PEi = KE + PE

KEi =2.02J

fk =13.72

KE=0

PEi =0

therefore (13.72 N + 2.02 J)/ 50N/m = x^2

Is this equation right? If so, how do I find x?

I tried to work it but I can't figure out how to add newtons and joules divided by N/m and end up with x in meters...
