The box of a well-known breakfast cereal states that one ounce of the cereal contains 128 Calories (1 food Calorie = 4186 J). If 1.95 % of this energy could be converted by a weight lifter's body into work done in lifting a barbell, what is the heaviest barbell that could be lifted a distance of 2.08 m?
