A.) The box of a well-known breakfast cereal states that one ounce of the cereal contains 107 Calories (1 food Calorie = 4186 J). If 2.03 % of this energy could be converted by a weight lifter's body into work done in lifting a barbell, what is the weight of the heaviest barbell that could be lifted a distance of 2.04 m?

B.) The latent heat of vaporization of H2O at body temperature (37.0°C) is 2.41E+6 J/kg. To cool the body of a 77.7 kg jogger [average specific heat capacity = 3460 J/(kg*°C)] by 1.50°C, how many kilograms of water in the form of sweat have to be evaporated?
