Answer:
441J
Explanation:
Given parameters:
Mass of book = 5kg
Height = 9m
Unknown:
Gravitational potential energy = ?
Solution:
The gravitational potential energy of a body is the energy due to the position of the body.
It is given as:
Gravitational potential energy = mass x acceleration due to gravity x height
Gravitational potential energy = 5 x 9.8 x 9 = 441J
