Answer:
73.575 Joules
Explanation:
The formula in getting the gravitational potential energy of an object is taken to be:
U = mgh
Where
U = gravitational potential energy, Joules
m = mass, kg
g = acceleration of earth due to gravity,
h = height from a reference point, m
Given:
m = 3 kg
h = 2.5 m
g = 9.81 (constant)
We can get the gravitational potential energy by using the formula shown.
By substituting the given values, we now have:
U = (3 kg)(9.81 )(2.5 m)
U = 73.575 Joules.
Therefore, the gravitational potential energy of a 3 kg box that is placed on a shelf that is 2.5 m high is equal to 73.575 Joules.
