hkellickA car has frozen over, covered with .05 inch of ice. Assuming that the driver gets into the car and starts the car up, warming the car up to a constant temperature of 85 degrees F, how long does it takes for the ice to melt off the top of the car. Assume that there is 1/16 inch of #4 Insulation (OK, I'm totally making this part up) connected to the roof and that the roof is composed of 1/8 inch of hardened steel.
How long would it take if the temperature increased linearly from 30 degrees F at ignition to 85 degrees F within 5 minutes?
(This silliness brought to you by a frozen car and a diseased mind. Though I've gotta think there has to be a way to solve this problem.)
