Question

A dockworker loading crates on a ship finds that a 20.0-kg
crate, initially at rest on a horizontal surface, requires a 75.0-N
horizontal force to set it in motion. However, after the crate is
in motion, a horizontal force of 60.0 N is required to keep it
moving with a constant speed. Find the coefficients of static
and kinetic friction between crate and floor.
