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.
