The rear window of a van is coated with a layer of ice at OC. The density of ice is 917 kg/m , and the latent heat of fusion of water is 3.35 x 105 J/kg. The driver of the van turns on the rear-window defroster, which operates at 12 V and 24 A. The defroster directly heats an area of 0.53 m of the rear window. What is the maximum thickness of ice above this area that the defroster can melt in 3.6 minutes? Number i Units
