With short-term efforts, a person weighing 75 kg can easily run up stairs to a height of 12 meters in 6 seconds. Determinant of the power developed by a person.

To determine the power of a person when running up stairs, we apply the formula: N = A / t = m * g * h / t.

Values of variables: m – human weight (m = 75 kg); g – acceleration due to gravity (g ≈ 10 m / s2); h (ladder height) = 12 m; t is the duration of the run (t = 6 s).

Let’s make a calculation: N = m * g * h / t = 75 * 10 * 12/6 = 1500 W (1.5 kW).

Answer: Man was able to develop a power of 1.5 kW.
