Question

A dock worker loading crates on a ship finds that a 24 kg crate, initially at rest on a horizontal surface, requires a 64 N horizontal force to set it in motion. However, after the crate is in motion, a horizontal force of 46 N is
required to keep it moving with a constant speed. The acceleration of gravity is 9.8 m/s2 . Find the coefficient of static friction between crate and floor.

Part B: Find the coefficient of kinetic friction.
