A man with a mass of 110 kg decides to lose weight by climbing the stairs in his office building several times a day. With his current daily activities and food intake, his weight is stable, but he would like to lose 0.5 kg per week without reducing food intake. Data shows that a person must burn 8000 Cal to lose 1 kg of mass (1 Cal = 4.19 x 103 J). If each story of the office building has...
