Solve the problem.The acceleration due to gravity g (in meters per second per second) at a height h meters above sea level is given by  where 6.374 × 106 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) Compare the value in (a) to the value of g(h) at sea level.

What will be an ideal response?


a)g(-86) ? 9.8211 m/sec2
b) g(0) ? 9.8208 m/sec2
