The world’s fastest elevator, in Taiwan’s Taipei 101 skyscraper,
ascends at the rate of 1010 m/min. Counterweights balance the
weight of the elevator’s car, so the motor doesn’t have to lift the car’s
weight. If the motor produces 330 kW of power, what’s the
maximum number of 67-kg people the elevator can accommodate?
(Your answer somewhat overestimates the actual rated load of 24
people.)
