a 70kg man successfully pushes a 200kg refrigerator up a 20 angle inclinded slope. he applies a force of 3kN, parallel to the surface of the incline, pushing northwest (north meaning up in this context). friction between the refrigerator and the surface of the incline is 300 Newtons. the normal force acting on the refrigerator is 1.842 kN. choose +x axis to point eastward +y axis to point upward. calculate the weight of the refrigerator
