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.

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )
