Answer:
7.5 J
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 = 0.17 × 9.8 × 4.5 = 7.497
We have the final answer as
7.5 J
Hope this helps you
