Only about 20% of the Calories we consume are used for mechanical work (i.e., moving the body around). Estimate how many granola bars (150 Cal per bar) an 85 kg person will burn if they climb vertically up theside of the Empire State Building.
height of Empire State Building, h = 443 m
unit conversion: 1 Cal = 4184 Joules
Problem 1.1. The Fahrenheit temperature scale is defined so that ice melts at
32°F and water boils at 212°F.
(a) Derive the formulas for converting from Fahrenheit to Celsius and back.
(b) What is absolute zero on the Fahrenheit scale?
Problem 1.2. The Rankine temperature scale (abbreviated °R) uses the same
size degrees as Fahrenheit, but measured up from absolute zero like kelvin (so
Rankine is to Fahrenheit as kelvin is to Celsius). Find the conversion formula
between Rankine and Fahrenheit, and also between Rankine and kelvin. What is
room temperature on the Rankine scale?
A painter drops a 3.09 kg can from a height of 10.0 m. What is K (in Joules) at a height of 2.84 m?

- When working on a PHYS 1510 weekly assignment, a student decided to get a medium double double coffee from Tim Hortons (a coffee made with two creams and two sugars). After drinking it, the student looked up the nutritional value of the drink, and was shocked to find it was listed as 230.0 kcal (230.0 nutritional calories). After drinking the coffee, they weighed 87.88 kg. To work off all the calories, the student decides to climb the stairs in their building. How many floors do they need to climb to burn off the entire drink? (do not include units) Assume all floors are 3.00 m apart from each other. Assume all nutritional energy is fully converted to potential energy. 1 kcal = 4184 Jarrow_forwardA 45-kg person drinks 5.6 × 102 g of milk, which has a caloric value of approximately 3.0 kJ/g.
