Question 1045948
.
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.) 
~~~~~~~~~~~~~~~~~~~~~~~~~~~


<pre>
{{{W[1]/W[2]}}} = {{{(R+200)^2/R^2}}},     ({{{W[1]}}} = weight on the Earth surface,  {{{W[2]}}} = weight 200 miles above the surface)

{{{160/W[2]}}} = {{{(4200/4000)^2}}},

{{{W[2]}}} = {{{160*(4000/4200)^2}}}.


Happy calculating!
