Question

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

Answer 1

Ball

Step-by-step explanation:

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

`Ug_(1)=18g\\`

The density of water is 1kg/liter, therefore

`Ug_(2)=(2*1)*8g\\\\Ug_(2)=16g\\`

Compare Ug1 to Ug2:

`Ug_(1) > Ug_(2)`
