The wheels of the refrigerator of the figure are stuck and will not turn. The refrigerator weighs 600 N. Assume a coefficient of friction between the wheels and the floor of 0.6 and determine the force necessary to cause the refrigerator to just start to move (impending motion). Also determine the maximum height h at which the force can be applied without causing the refrigerator to tip over.
