The Burj Khalifa in Dubai is the world\'s tallest building. The structure is 828 m (2,716.5 feet) and has more than 160 stories. A tourist is obviously using the elevator to reach their hotel room and after a long ride finally arrives at the correct floor where the tourist has -199000 J of potential energy. If the 188 lb tourist has zero potential energy at the top of the building, how high is the hotel room from the ground? The acceleration due to gravity is 9.81 m/s2.
