A modern sculpture has a large horizontal spring, with a spring constant of 276 N/m, that is attached to a 49.0-kg piece of uniform metal at its end and holds the metal at an angle of ? = 52.0° above the horizontal direction. The other end of the metal is wedged into a corner as shown. By how much has the spring stretched in meters?
