When you skid to a stop on your bike, 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 his back tire, which supports half the 70 kgkg combined mass of the bike and rider, leaving a skid mark that is 36 cmcm long. Assume a coefficient of kinetic friction of 0.80.
