We use a cable with linear mass density of 0.1 kg/m in order to lift a piano of total mass of 1000 kg to the fifth floor of a building at 25 m above the ground. An additional 5 m of cable are needed to wrap around the piano so it can be securely lifted. Find the total amount of work done (in kilojoules, kJ) to lift the piano to the fifth floor of the building. (Note that 1 kJ = 1000 J.) Round your answer to the nearest tenth and omit units.
