Chapter 18, Problem 89P
An athlete needs to lose weight and decides to do it by “pumping iron.” (a) How many times must an 80.0 kg weight be lifted a distance of 1.00 m in order to burn off 1.00 lb of fat, assuming that that much fat is equivalent to 3500 Cal? (b) If the weight is lifted once every 2.00 s, how long does the task take?

A less than youthful 80.6 kg physics professor decides to run the 26.2 mile (42.195 km) Los Angeles Marathon. During his months of training, he realizes that one important component in running a successful marathon is carbo-loading, the consumption of a sufficient
quantity of carbohydrates prior to the race that the body can store as glycogen to burn during the race. The typical energy requirement for runners is 1 kcal/km per kilogram of body weight, and each mole of oxygen intake allows for the release of 120 kcal of energy by
oxidizing (burning) glycogen.
(a) If the professor finishes the marathon in 5:15:00 h, what is the professor's oxygen intake rate, in liters per minute, during the race if he metabolizes all of the carbo-loaded glycogen during the race and the ambient temperature is 21.5°C?

Read the problem statement again carefully. Is the air at standard temperature and pressure during the marathon? How would this affect the volume of 1 mol of oxygen? L/min

You are watching a new bridge being built near your house. You notice during the construction that two concrete spans of the bridge of total length L; = 270 m are placed end to end so that no room is allowed for expansion (figure (a)). In the opening
storyline for the thermodynamics chapter, we talked about buckling sidewalks. The same thing will happen with spans on bridges if allowance is not made for expansion (figure (b)). You want to warn the construction crew about this dangerous situation, so
you calculate the height y to which the spans will rise when they buckle in response to a temperature increase of AT = 19.0°C.

- An open cylinder of air has a radius of 38.0 cm and a height of 50.0 cm, as shown in figure (a). 50.0 cm Ah The air pressure is 1.00 atm and the temperature is 13.5°C. A 25.0 kg piston is then lowered onto the cylinder, forming an airtight seal, as shown in figure (b). The air inside is compressed until the piston reaches equilibrium (mechanical and thermal), and at this point the piston is a height h; from the bottom of the cylinder. Lastly, a 27.5 kg dog steps onto the piston, and the air in the cylinder again compresses, as show in figure (c). After reaching equilibrium, the air inside is again at 13.5°C, and the height of the piston decreases a distance Ah as shown.

The two joined wires are connected to fixed points a total distance of 4.00000 m apart. When both wires are at a temperature of 43.0°C, each wire has an unstretched length of 2.00000 m, and the tension in each is negligible. The first wire is made of steel and extends from x = -2.00000 m to x = 0, and the second is made of brass and extends from x = 0 to x = 2.00000 m. The temperature of both wires is then lowered to 18.0°C, and the wires stay joined together as they cool. The steel wire is composed of an alloy that has an average coefficient of linear expansion of 1.10 x 10-5 (°C) -1 and a Young's modulus of 2.00 x 1011 N/m².
