To have a PE of 425J I need to lift the box 2,816 m from the floor.
PE is the energy that the bodies have stored by being at a certain height.
Formula: PE= m·h·g
where:
m= mass (kg)
h= height (m)
g=gravity acceleration =9,8 m/s²
PE= potential energy (J)
so h = EP/(m*g) = 425J/(15,4 kg*9,8 m/s²) = 2,816 m
