ANSWER:Solution 9P Introduction Given in the question that 25% of chemical energy is converted to mechanical energy. Therefore, remaining (100-25)% = 75% will be mechanical energy as Total energy = Chemical energy+mechanical energy. To calculate increase in body temperature, we need to use the equation Q = ms, where Q is amount of heat involved, m is the mass of J cyclist, s is specific heat of human body = 3400 kg. C, is increase in body temperature. Step 1: Total metabolic power is = 480 W Now, 75% of total metabolic power is converted to thermal energy.
