D X M 1986B2 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 Determine expressions for the following quantities in terms of M X D h and g Note that these symbols do not include the spring constant al The time elapsed from the instant the block leaves the table to the instant it strikes the floor b The horizontal component of the velocity of the block just before it hits the floor c The work done on the block by the spring d The spring constant
