Answer:
h = 20 m
Explanation:
Gravitational Potential Energy
Gravitational potential energy (GPE) is the energy stored in an object due to its vertical position or height in a gravitational field.
It can be calculated with the equation:
U=m.g.h
Where m is the mass of the object, h is the height with respect to a fixed reference, and g is the acceleration of gravity or [tex]9.8 m/s^2[/tex].
The weight of an object of mass m is:
W = m.g
Thus, the GPE is:
U=W.h
Solving for h:
[tex]\displaystyle h=\frac{U}{W}[/tex]
The weight of the owl is W=40 N and its GPE is U=800 J.
[tex]\displaystyle h=\frac{800}{40}=20[/tex]
h = 20 m
