For a physics lab experiment, four classmates run up the stairs from the basement to the top floor of their physics building€”a vertical distance of 16.0 m. The classmates and their masses are: Tatiana, 50.2 kg; Bill, 68.2 kg; Ricardo, 81.8 kg; and Melanie, 59.1 kg. The time it takes each of them is shown in Fig. P6.92.

(a) Considering only the work done against gravity, which person had the largest average power output? The smallest?

(b) Chang is very fit and has mass 62.3 kg. If his average power output is 1.00 hp, how many seconds does it take him to run up the stairs?
