The elevator with a mass of 200 kg with an input power of 4.5 kW with a constant speed, takes 2 passengers, whose average mass is 50 kg each, from the first floor to the tenth floor of the building in 40 seconds. If the height of each floor of the building is 4 meters, how many kilowatts is the useful power of the elevator?
