The acceleration due to gravity g (in meters per second per second) at a height h meters above sea level is given by g(h)=3.99x10^14/(6.374x10^6+h)^2 where 6.374 10^6 is the radius of Earth in meters. Death Valley in California is 86 m below sea level

a) Find the value of g(h) at Death Valley to four decimal places.

b) Find the value of g(h) at sea level to four decimal places.

c) Is your acceleration quicker in Death Valley or at sea level?
