A dockworker loading crates on a ship finds that a 34.0-kg crate, initially at rest on a horizontal surface, requires a 72.0-N horizontal force to set it in motion. However, after the crate is in motion, a horizontal force of 51.0 N is required to keep it moving at a constant speed. Find the coefficients of static and kinetic friction between the crate and floor.

Your turn to try.
{F_s} = {\mu _s}N
N=mg.
{F_k} = {\mu _k}N
{F_s}=72 N
{F_k}=51 N
N=mg.
{F_k} = {\mu _k}N
{F_s}=72 N
{F_k}=51 N
