How much gravitational potential energy is stored in the great pyramids of chips given that its mass is about 7×10 to the 9th kg and it center of mass is the early 6.5 m above the surrounding ground

Answer :

Answer:

[tex]4.46\cdot 10^{11} J[/tex]

Explanation:

The gravitational potential energy of an object is given by:

[tex]U=mgh[/tex]

where

m is the mass of the object

g is the acceleration of gravity

h is its height above the ground

In this problem, we have

[tex]m=7\cdot 10^9 kg[/tex] is the mass of the pyramid

[tex]g=9.8 m/s^2[/tex]

h = 6.5 m is the height of the center of mass above the ground

Solving the equation, we find

[tex]U=(7\cdot 10^9)(9.8)(6.5)=4.46\cdot 10^{11} J[/tex]
