A skyscraper in Manhattan has an elevator that weighs 1000 kg when loaded. The elevator is lifted at a constant rate to 480m above the ground by an electric winch motor. The drum of the winch motor is a solid uniform cylindrical drum in which a steel cable can wrap around it. The mass of the drum is 500 kg and has a diameter of 1 m. It takes the elevator a total of 120 s to get to the...
