Question

if you exert a force of 700 N to walk 6m up a flight of stairs in 6s how much power do you lose?

Answer 1

Answer:

700 watts

Explanation:

From the question, it is given that;

Force = 700N

Distance = 6m

Time = 6s

First step: we derive the formula that relates Power, distance and time, from first principle

$Power = \frac{Energy}{Time}$

But Energy is Force X Distance

$Power = \frac{Force X Distance}{Time}$

$Power = \frac{(700) X (6)}{6}$

Power = 700 watts

The power you will lose after walking the stairs is 700 watts
