A latest record for running the stairs of the Empire State Building was set on February 3, 2003. The 86 flights, with a net of 1576 steps, was run in 9 minutes and 33 seconds. Consider a case where a man ran up 1600 steps of the Empire State Building in the 10 minutes and 59 seconds. When the height gain of each step was 0.20 m, and the man's mass was 57.0 kg, determine his average power output throughout the climb? Give your answer in both watts and horse-power.
