Answer:
58,800 J
Step-by-step explanation:
The gravitational potential energy of a body can be found by using the formula
GPE = mgh
where
m is the mass
h is the height
g is the acceleration due to gravity which is 9.8 m/s²
From the question we have
GPE = 200 × 9.8 × 30 = 58,800
We have the final answer as
58,800 J
Hope this helps you
