How much power does it take for a student to climb a flight of stairs if their mass is 75 kg, the height of the stairs is 10 meters, and it takes them 25 seconds to climb?

Hi there!

We can begin solving for the work necessary using the following:

[tex]W = \Delta U = mg\Delta h[/tex]

W = Work (J)

Δh = change in height (10 m)
m = mass (75 kg)
g = acceleration due to gravity (9.8 m/s²)

Plug in the givens:

[tex]W = 75 \cdot 9.8 \cdot 10 = 7350 J[/tex]

Now, we can solve for power with this equation:
[tex]\large\boxed{P = \frac{W}{t}}[/tex]

P = Power (Watts)

W = Work (J)
t = time (s)

Plug in the values:


[tex]P = \frac{7350}{25} = \boxed{294 W}[/tex]
