1.A dockworker loading crates on a ship finds that a 175 kg crate, initially at rest on a horizontal surface, requires a 500 N horizontal force to set it in motion. However, after the crate is in motion, a horizontal force of 450 N is required to keep it moving with a constant speed. Find the coefficients of static and kinetic friction between crate and floor. (a) the coefficient of static friction = and (b) the coefficient of kinetic friction =
