AA 62. Gravity Near the Moon We can use Newton's Law of Gravity to measure the gravitational attraction between the moon and an algebra student in a spaceship located a distance x above the moon's surface: 350 F(=) 2 Here F is measured in newtons (N), and a is measured in millions of meters. > (a) Graph the function F for values of a between 0 and 10. (b) Use the graph to describe the behavior of the gravitational attraction F as the distance r increases
