Problem 1 (The Rope-Around-the-World Problem)

A rope goes around the earth at the equator three feet above the ground. We assume the earth is a perfect sphere of radius 25,000 miles. If we now drop the rope to the ground and pull up the slack, how much slack will there be ? You might guess at the amount of slack before you solve the problem.
