Hi,
w=Cr^-2 , where C is a constant, and r is the <u>distance that the object is from the center of Earth.</u> 
Part 1a: {{{r = sqrt(C/w)}}}
Part 1b: {{{C = wr^2 = 200*(3963)^2 }}}= 3,141,073,800   
Part 1c: 
 i.Fine w when r = 1,388   {{{w = C/r^2}}}
 w = {{{3141073800/(1388)^2= 3141073800/1926544}}} = 1630.4189 
ii.  i.Fine w when r = 16730 + 3963 = 20,693ft from center of earth   {{{w = C/r^2}}}
 w = {{{3141073800/(20693)^2 }}}
