Popeye the Sailor man, who has a mass of 85 kg, ran ( at a constant rate ) up a flight of stairs that are 3.55 m high in 6 seconds. How many watts of power did he generate during his run ?

Respuesta :

Given data

*The given mass of the Sailorman is m = 85 kg

*The given height is h = 3.55 m

*The given time is t = 6 s

*The value of the acceleration due to gravity is

[tex]g=9.8m/s^2[/tex]

The formula for the power generated by the Sailorman during his run is given as

[tex]\begin{gathered} P=\frac{W}{t} \\ =\frac{\text{mgh}}{t} \end{gathered}[/tex]

*Here W is the work done

[tex]\begin{gathered} P=\frac{85\times9.8\times3.55}{6} \\ =492.85\text{ W} \end{gathered}[/tex]
