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
