A 1000N crate is being pushed across a level floor at a constant seed by Force F which equals 300N at an angle 20 degrees below the horizontal. What is the coefficient of kinetic friction between the crate and floor? Also, if it is pulling the block at an angle 20 degrees above the horizontal, what is the acceleration of the crate?
