newtons law of motion, Physics

a dock worker loading crates on a ship finds that a 24kg crate, intially at rest requires a 65N horizontal force to set it in motion.However,after the crate is in motion, a horizontal of 50N is required to keep it moving with a constant speed. The acceleration of gravity is 9.8m/s^2. Find the coefficient of static friction between crate and floor.
