I was in the middle doing my homework perfectly fine until I encountered this question.

How many watts of power does a man with a weight of 600.0 N have when he climbs a flight of stairs 3.0 m high in 5.0s?

The problem I am having is the weight part because it is my first time encountering a weight with Newtons.

Steps I took in an attempt to find the answer:

$P = \frac{\Delta E}{\Delta t}$   $E_g = mgh$

$P = \frac{\Delta E}{5}$  $E_g = m(9.8)(3)$

Is there any way to convert that 600.0 N into kilograms?

Weight or the Force of gravity = mass times acceleration of gravity Fg=m*g 600.0N = m *$ 9.8 m/s^2 $ $600.0/9.8 = m $ m=61.
