Problem: A dock worker loading crates on a ship finds that a 25 kg crate, initially at rest on a horizontal surface, requires a 90 N horizontal force to set it in motion. However, after the crate is in motion, a horizontal force of 51 N is required to keep it moving with a constant speed. The acceleration of gravity is 9.8 m/s2.
Part A: Find the coefficient of static friction and coefficient of kinetic friction between crate and floor.
I want help to find the coefficient of static friction and coefficient of kinetic friction between crate and floor.
