In many engineering uses, the value of "g", the acceleration due to gravity, is taken as a constant. However, g is actually dependent upon the distance from the center of the Earth. A more accurate expression for g is:
\(g= g0 (Re/(Re+A))^2\)
Here, g0 is the acceleration of gravity at the surface of the Earth, A is the altitude, and Re is the radius of the Earth, approximately 6,380 kilometers. What is the value of g at an altitude of 20 miles in unites of meters per second squared?
