Suppose that the average U.S. household uses 12600 kWh (kilowatt-hours) of energy in a year. If the average rate of energy consumed by the house was instead diverted to lift a 1250 kg car 15.8 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 4.00 x 10 kg, to a cruising altitude of 9.17 km? Number S
