The acceleration due to gravity,
, at a height
meters above sea level is given by
.
(a)
\At sea level .
Substitute in
.
The acceleration due to gravity at sea level is .
(b)
\Substitute in
.
The acceleration due to gravity at the top of the Willis Tower is .
(c)
\Substitute in
.
The acceleration due to gravity on the peak of Mount Everest is .
(d)
\The function
Degree of the numerator of the function and degree of the denominator
.
Since the degree of the numerator is less than degree of the denominator, horizontal asymptote is .
-axis is horizontal asymptote.
(e) Solve .
has no solutions since the numerator is a nonzero constant, so it cannot be never to 0, which means no matter how far the object is from the surface of the earth, there is always a nonzero acceleration due to gravity. How ever, if the object is
very far away from the surface of the earth, even the acceleration due to gravity is non zero, it is negligible, so we assume it is
\zero.
