# Newton's Law of Gravitation can be used to show that if an object weighs w pounds on the surface of the earth, then its weight at a distance x from the center of the earth is W(x) = wR? (for x > R), where R = 3960 miles is the radius of the earth. Estimate the altitude at which a 140-lb pilot would weigh 139.5 lb. (Use decimal notation. Give your answer to two decimal places.)
