I am having trouble with this word problem.
Weight of an Astronaut. The weight W of an object varies inversely as the square of the distance d from the center of the earth. At sea level (3978 mi from the center of the earth), an astronaut weighs 220lbs. Find his weight when he is 200 mi above the surface of the earth and the spacecraft is not in motion.
y=k 1/x^2
220lbs.+k 1/3978^2
k=3481386480
Where do I go from here to solve the weight?[/list]
