Question

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 1

Answer:

$4.46\cdot 10^{11} J$

Explanation:

The gravitational potential energy of an object is given by:

$U=mgh$

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

$m=7\cdot 10^9 kg$ is the mass of the pyramid

$g=9.8 m/s^2$

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

Solving the equation, we find

$U=(7\cdot 10^9)(9.8)(6.5)=4.46\cdot 10^{11} J$
