Question

d. Suppose you try to "lose" the calories gained when eating the "Big Mac meal" by exercising - say by doing an equivalent amount of work in the gymnasium by lifting a 50 kg "weight" a vertical distance of 5 feet (convert to metre). (i) To compensate for the calories gained by eating the Big Mac meal, how much total work in Joules must be expended by exercising? Exercise work equivalent to ◻ Joules (ii) How much work is expended in lifting the 50 kg weight 5 feet once? 5 feet = ◻ metre Work to lift 50 kg mass a vertical distance of 5 fee ◻ (iii) How many times must you raise the "weight" to expend the total energy gained from food?
