Answer:
1960 Joules
Step-by-step explanation:
The formula for Gravitational Potential Energy (GPE) is:
GPE = mgh
Where
m is the mass in kg
g is the gravitational field strength (in earth, it is 9.8)
h is the height in meters
In the questions, it is given
mass = 10 kg
height = 20 m
g = 9.8
Substituting, we get:
GPE = mgh
GPE = (10)(9.8)(20) = 1960 Joules
