An elevator car including the passengers has a mass of 1100 kg and travels downwards at constant speed of 4.000 m/s for 32.00 m. The force of friction averaging 80.00 N acts on the elevator. The work done by the force of gravity; the work done by the force of friction; and the work done by the cable supporting the elevator during the 32.00 m excursion were (in that order, in kJ):

Answer: 345.0; -2.560; -342.4
