The person shown in Figure 2.1 (page 27) is pushing on a refrigerator that sits on a level floor. Assume the section of the floor underneath the refrigerator is very slippery so that the only horizontal force on the refrigerator is due to the person. If the force exerted by the person has a magnitude of 120 N and the refrigerator has a mass of 180 kg, what is the magnitude of the refrigerator€™s acceleration?
