A horizontal force of 150 N is used to push a 33.0 kg packing crate a distance of 6.65 m on a rough horizontal surface. If the crate moves at constant speed and the work done is 997.5 joules. What is the coefficient of kinetic between the crate and the surface.
February 18, 2010

Physics
The answer is 433.719 joules. You find the sum of the x forces by taking 110*cos31.1 - 19.5*9.81*.156 which gives you 64.35 Newtons. You put that answer in the Work formula. Work equals force * distance so take 64.35*6.74 meters and you get your answer, 433.719 Joules.
