Assume that the average mass of each of the approximately 1 billion people in china is 55 kg. assume that they all gather in one place and climb to the top of 2 m high ladders. how muchhas the center of mass of the earth (me = 5.90×1024 kg) displaced as a result?

Explanation:

The equation to calculate the center of mass of a particle system is:

In this case we can arrange for one dimension, assuming the geometric center of the Earth and the ladder are on a line, and assuming original center of mass located at the Earth's geometric center:

Where:

is the mass of the Earth

is the mass of 1 billion people

is the radius of the Earth

is the distance between the center of the Earth and the position of the people (2 m above the Earth's surface)

This is the displacement of Earth's center of mass from the original center.

e

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.

i really dont know but i will try okay.

so i think u would just add all them up and get your answer..
