Compute all parts of given problem:
Problem: A dock worker loading crates on a ship finds that a 24 kg crate, initially at rest on a horizontal surface, requires a 71 N horizontal force to set it in motion. However, after the crate is in motion, a horizontal force of 57 N is required to keep it moving with a constant speed. The acceleration of gravity is 9.8 m/s+.
Part I: Find the coefficient of static friction between crate and floor.
Part II: Find the coefficient of kinetic friction.
I need help to find the coefficient of static friction between crate and floor.
