A uniform rectangular 86.07 kg refrigerator with height h = 2.441 m and width w is pushed at a constant velocity across a level floor. The refrigerator is pushed in the horizontal direction halfway between the floor and the top of the refrigerator and the refrigerator does not tip over while being pushed. The coefficient of kinetic friction between the refrigerator and the floor is 0.4699. What is the width w of the refrigerator?
