Interpretation Introduction Interpretation: The authenticity of the given assumption is to be determined. Concept Introduction: The potential energy gained by the person is less than the energy7 created by calorie eaten by them leads to no weight gain. To determine: If the given assumption is true or not. Explanation Given The weight of the person is 201 lb . The height of the stairs is 45 ft . The number of times person walk upstairs per day is 20 . The calorie gained by eating French fries is 245 Cal . The assumption is that the person will not gain weight by eating this amount of calorie. The conversion of weight from lb into g is done as, 1 lb = 453.6 g Hence, the conversion of weight from 201 lb into grams is, 201 lb = 201 × 453.6 g = 9.117 × 10 4 g The conversion of height from ft into m is done as, 1 ft = 1 3.28 m Hence, the conversion of height from 45 ft into m is, 45 ft = 45 × 1 3.28 m = 13.72 m The potential energy gained by the person in walking upstairs one time is calculated by using the formula, Potential energy = m g h Where, m is the mass of the person
