PLS ANSWER

Respuesta :

Answer:

Power, P = 80 W

Step-by-step explanation:

We have,

Weight of athlete is 960 N

It runs through a flight of stair case in 2 mins or 120 second

There are 100 stairs and each stair case has a length of 100 mm  or 0.1 m

Power is given by :

[tex]P=\dfrac{Fd}{t}[/tex]

d is distance

For 100 stairs,

So,

[tex]P=\dfrac{960\times 100\times 0.1}{120}\\\\P=80\ W[/tex]

So, the power of an athlete is 80 watts.
