A frictionless, vertical wire has two metal beads on it. The beads are held 30 cm apart by horizontal magnets. If the top magnet is removed, the first bead falls under the force of gravity and strikes the second. The first bead bounces back up to a height of 10cm and the second is knocked free of the magnet and falls downward. If the two beads each have a mass of 49.7 g, what is the kinetic energy of the second immediately after impact?
