The food calorie (also known as nutritional calorie and large calorie) is a term used in place of what is otherwise known as a kilocalorie (kcal). Not surprisingly, the food calorie is used to represent units of energy associated with eating, as in "An average hot dog with ketchup and a bun contains 315 calories." A hungry person woke up this morning and went to the McDonald's down the street to eat a Full Big Breakfast, which included hotcakes, eggs, and a large biscuit. According to figures published by McDonald's, the Big Breakfast contains 1090 calories (meaning food calories). Required:
a. How many stairs (of height 7.25 inches) would a person of mass 140.0 lbm have to climb in order to expend the calories consumed in the Big Breakfast?
b. How many stairs (of height 7.25 inches) would a person of mass 180.0 lbm have to climb in order to expend the calories consumed in the Big Breakfast?
