One end of a spring is attached to a solid wall while the other end just reaches to the edge of a horizontal, frictionless tabletop,which is a distance h above the floor. A block of mass M is placed against the end of the spring and pushed toward the wall until thespring has been compressed a distance X, as shown above. The block is released, follows the trajectory shown, and strikes the floor ahorizontal distance D from the edge of the table. Air resistance is negligible.What is the spring constant?
