Question

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 ?

Answer 1

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

`g=9.8m/s^2`

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

`\begin{gathered} P=(W)/(t) \\ =\frac{\text{mgh}}{t} \end{gathered}`

*Here W is the work done

`\begin{gathered} P=(85*9.8*3.55)/(6) \\ =492.85\text{ W} \end{gathered}`
