.
The weight of a body w varies inversely with the square of its distance from the center of Earth d.
If a person weighs 160 pounds on the surface of Earth ,what is the person’s weight 200 miles above the surface?
(Assume that the radius of Earth is 4000 miles.)
~~~~~~~~~~~~~~~~~~~~~~~~~~~
= , ( = weight on the Earth surface, = weight 200 miles above the surface)
= ,
= .
Happy calculating!
