Question

Swashbuckler Inigo Montoya has a mass of 75 kg. It takes him 6.8 seconds to run up two flights of stairs which results in him being 7 m above his starting point. How much power does Montoya exhibit in his run up the stairs?

Answer 1

The answer to your question is 757.4 W

Step-by-step explanation:

Data

mass = 75 kg

time = 6.8 s

height = 7 m

Power = ?

Formula

Power = Work/time

Process

1.- Calculate the work

Work = Force x distance

Force = 75 x 9.81

Force = 735.8 N

Work = 735.8 x 7

Work = 5150.25 J

2.- Calculate the power

Power = 5150.25 / 6.8

Power = 757.4 W
