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 the spring has been compressed a distance X, as shown above. The block is released, follows the trajectory shown, and strikes the floor a horizontal distance D from the edge of the table. Air resistance is negligible. What is the horizontal component of the velocity of the block just before it hits the floor?

Question
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 the
spring has been compressed a distance X, as shown above. The block is released, follows the trajectory shown, and strikes the floor a
horizontal distance D from the edge of the table. Air resistance is negligible.
What is the horizontal component of the velocity of the block just before it hits the floor?
