5. For most automobiles, the number of miles per gallon
decreases as highway speed increases. Fuel economy drops as
speeds increase from 55 to 65 mph, then decreases further as
speeds increase to 75 mph. Explain why this is the case.
Please state the following (apply your problem solving strategy):
A. REASON: State and describe the overall physical principles you think
apply to solve this problem.
3. ASSESS: What is the energy content in kJ of gasoline in 1 g of fuel?
2. If we wanted to supply a world of 10 billion people with an average demand of electricity at 1 kW per person, what
surface area of photovoltaic arrays would be required? Compare this to the size of a known city, state or country.
Suppose that the average U.S. household uses 10100 kWh10100 kWh (kilowatt‑hours) of energy in a year. If the average rate of energy consumed by the house was instead diverted to lift a 1.80×103 kg car 11.3 m into the air, how long would it take?
1. car: ______ seconds?
Using the same rate of energy consumption, how long would it take to lift a loaded Boeing 747 airplane, with a mass of 4.10×105 kg, to a cruising altitude of 9.92 km?
2. airplane: ______ seconds?
