Answer:
7350 J
Explanation:
The potential energy stored in an object is
[tex]E_p = mgh[/tex]
where
m is its mass
g is the acceleration of gravity
h is the heigth of the object relative to the ground
In this problem:
m = 30 kg is the mass of the object
[tex]g=9.8 m/s^2[/tex]
h = 25 m is the height
Substituting,
[tex]E_p = (30)(9.8)(25)=7350 J[/tex]
