In physics, it is established that the acceleration due to gravity, g (in meters/sec2 ), at a height h meters above sea level is given by
g(h) = 3.99 * 1014/(6.374 * 106 + h) 2
where 6.374 * 106 is the radius of Earth in meters. (a) What is the acceleration due to gravity at sea level? (b) The Willis Tower in Chicago, Illinois, is 443 meters tall. What is the acceleration due to gravity at the top of the Willis Tower? (c) The peak of Mount Everest is 8848 meters above sea level. What is the acceleration due to gravity on the peak of Mount Everest? (d) Find the horizontal asymptote of g(h). (e) Solve g1h2 = 0. How do you interpret your answer?
It takes Earth 365 days to complete one orbit around our sun. Knowing that the magnitude of the average acceleration the Earth experiences over half an orbit is 3.78×10−3m/s2, what is the average speed with which it travels? Express your answer in m/s.
