You are driving down a highway on a sunny 7°C, fall day. The sun heats the 1m², flat, steel hood of your car to 93°C. Just as you enter a tunnel, your engine makes an odd noise. You slow to a constant speed of 30 miles per hour through the 1 mile long tunnel. At the exit of the tunnel, you pull over to look under the hood. If the hood must be below 60°C to prevent burning your hand, can you safely touch the hood with your bare hand? (Note: The thickness of the hood is 2.5 mm. Neglect any outside sources of heating, such as the engine that may still be warm.)
