Answer:
13.72 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 = 2 × 9.8 × 0.7
We have the final answer as
13.72 J
Hope this helps you
