Dane is holding an 8 kilogram box 2 metres above the ground. how much energy is in the box's gravitational potential energy store? assume dane is on earth, where g = 10 n/kg.

156.8 Joules of energy is in the box's gravitational potential energy store

Explanation:

Given:

Mass of the box Dane is holding = 8 Kilograms

Height at which Dane is holding the box above the ground= 2 metres

To Find:

Gravitational potential energy in the box=?

Solution:

gravitational potential energy is the work done per mass on a object to move that object from one fixed location to to another location against gravity.Its unit is joules or J

Thus  Gravitational potential energy is  represented as,

where

is the gravitational potential energy

m is the mass

h is the height

g is the gravitational force( 9.8 )

Now substituting the given values,
