Which object has more potential energy : a 3kg ball at a height of 6 meters or a 2-liter bottle of water at a height of 8 meters

Respuesta :

Answer:

Ball

Explanation:

We can set a system of equations for the objects and the systems:

[tex]Ug_{1}=18g\\[/tex]

The density of water is 1kg/liter, therefore

[tex]Ug_{2}=(2*1)*8g\\\\Ug_{2}=16g\\[/tex]

Compare Ug1 to Ug2:

[tex]Ug_{1} > Ug_{2}[/tex]
