it atis frirts biventin fines A dockworker loading crates on a ship finds that a 31kg crate, initially at rest on a horizontal constant speed. Find the coefficients of static and kinetic friction between crate and floor. static friction kinetic friction crate, initially at rest on a horizontal surface, requires a 72N horizontal force to set it in motion. However, after the crate is in n friction between crate and floor. A dockworker loading crates on a ship finds that a 31kg crate, initially at rest on a horizontal surface, constant speed. Find the coefficients of static and kinetic friction between crate and floor. static friction kinetic friction horizontal surface, requires a 72-N horizontal force to set it in motion. However, after the crate is in motion, a floor. after the crate is in motion, a horizontal force of 52N is required to keep it moving with a
