Question: You are pushing a refrigerator across the floor of your kitchen. You exert a horizontal force of 327 N for 7.1 s, during which time the refrigerator moves a distance of 3.3 m at constant velocity.
Part I: What is the total work (by all forces) done on the refrigerator?
Part II: What is the work done by friction?
Please use as much detail as possible in answer, thank you.
