On a cold winter morning you step outside to get into your car and drive to work. Your car's windshield is covered with ice at −14.3°C. If the area of the windshield is 1.40 m2 and it takes 1.77  105 J of heat to melt the ice, how thick was the ice covering the windshield? The latent heat of fusion of ice is 334 kJ/kg, the specific heat of ice is 2092 J/(kg · °C) and its density is 917 kg/m3 (answer in m).
