Final Answer must be a decimal or whole numbers only!!!
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
Solve the following problem. Round off the final answer to three decimal places.
A popular web site state that a 200 pound person will burn 450 calories/hour bicycling
(moderate effort) and 650 calories/hour rock climbing (ascending). A 150 pound person
decides to start a training routine in which she will bicycle for 45 minutes, 3 times a week and
rock climb for 1.50 hours every weekend. How many calories will she have burned after 8 weeks
of training (assuming she consumes at the same rate)?

- 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.

The metal bar has a specific heat that is a function of temperature:c(T) = A + αT, where A = 380 J/(kg⋅K) and α = 9.9 J/(kg⋅K2). Note the metal bar does not change in volume as it is heated. Calculate the amount of heat Q in joules required to raise the temperature on the metal bar as stated.
