###### Question:

Suppose that the average U.S. household uses 14600 kWh (kilowatt-hours) of energy in a year. If the average rate of energy consumed by the house was instead diverted to lift a 2130 kg car 11.3 m into the air, how long would it take? Number Using the same rate of energy consumption, how long would it take to lift a loaded 747, with a mass of 3.90 105 kg, to a cruising altitude of 9.92 km? Number
