Question

The weight of a body varies inversely as the square of its distance from the center of the earth. If the radius of the earth is 3500 miles, how much would a 180-pound man weigh 750 miles above the surface of the earth?

Answer 1

3,500 + 750 = 4,250

Weight = (3,500 / 4,250)^2 * 180 = 0.678200692 * 180 =

122.08 pounds
