A man pushes a refrigerator of mass m = 75 kg with an constant force F as shown in the figure and moves it a distance d = 8.0 m on a shop floor. The refrigerator is moved at a constant speed v = 1.5 m/s. The coefficient of kinetic friction k between the refrigerator and the floor is equal to 0.12 a. (4) Draw a free body diagram for the refrigerator. b. (5) Calculate the work Wf done by friction on the refrigerator. c. (6) Use the work-kinetic energy theorem to calculate the net work Wnet on the refrigerator. d. (5) Calculate the work WF the man does in moving the refrigerator e. (5) Calculate the rate P (power) with which the man does work on the refrigerator.
