Newton's law of gravitation can be used to show that if an object weighs pounds on the surface of the earth, then its weight at a distance x from the center of the earth is w(x)= (for x≥ where =3960 miles is the radius of the earth. estimate the altitude at which a 120- lb pilot would weigh 119.5 lb. (use decimal notation. give your answer to two decimal places.)
