When you skid to a stop on a bicycle, you can significantly heat the small patch of tire that rubs against the road surface. Suppose a person skids to a stop by hitting the brake on the back tire, which supports half of the combined mass (which is 75kg) of the bike and rider, leaving a skid mark that is 40 cm long. Assume a coefficient of kinetic friction of 0.80. How much thermal energy is deposited on the tire and road surface?
