The radius of the earth is roughly 4,000 miles, and an object located x miles from the center of the earth weighs w(x) 1b, where w(x) =

Ax if x ≤ 4,000
B/x^2 if x 4,000

and A and B are positive constants. Assuming that w(x) is continuous for all x, what must be true about A and B? Sketch the graph of w(x). The radius of the earth is roughly 4,000 miles, and an object located x miles from the center of the earth weighs w(x) 1b, where w(x) =
