3. We all know that the hood of a car gets extremely hot in the summertime when a bright sun is shining on it. Suppose that a certain hood weighs 22.8 pounds and is composed of pure iron. If the specific heat of the iron is 0.450 J/g °C, what is the final temperature of the hood if it is heated from 20.0 °C by the addition of 4.0 x 102 kJ of sunlight? (Recall that 1 pound = 0.4536 kg)
