A 0.390-kg box is placed in contact with a spring of stiffness 4.138x103 N/m. The spring is compressed 4.00x10'2 m from its unstrained length. The spring is then released, the block slides across a frictionless tabletop, and it flies through the air. The tabletop is a height of 1.330 m above the oor. \\\\\\\\\\\\\\ > d (the drawing is not to scale) What is the potential energy stored in the spring when it is compressed? one What is the kinetic energy of the block just before it leaves the table but a:er it is no longer in contact with the spring? What is the kinetic energy of the block just before it hits the floor? one How much time elapses between the time when the block leaves the table and the time just before the block hits the floor? one What distance, d, from the edge of the table does the block hit the floor? om
