The gravitational potential energy of the ball changes by about
37000 J

<h3>Further explanation</h3>
Let's recall the formula of Gravitational Potential Energy as follows:

<em>Ep = Gravitational Potential Energy ( Newton )</em>
<em>m = Object's Mass ( kg )</em>
<em>g = Gravitational Acceleration ( m )</em>
<em>h = Height ( m )</em>
Let us now tackle the problem !

<u>Given:</u>
mass of wrecking ball = m = 1400 kg
length of the cable = L = 20 m
angle with the vertical = θ = 30.0°
<u>Asked:</u>
gravitational potential energy = Ep = ?
<u>Solution:</u>






<h3>Conclusion:</h3>
The gravitational potential energy of the ball changes by about
37000 J
