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

700 watts

Step-by-step 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 = (Energy)/(Time)`

But Energy is Force X Distance

`Power = (Force X Distance)/(Time)`

`Power = ((700) X (6))/(6)`

Power = 700 watts

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