Imagine you have just witnessed a small avalanche on a mountain while skiing, and two slushy snowballs just crashed together in a perfectly inelastic collision. they are moving as one larger snowball, as a combined mass. before the collision, snowball a was 7 kg and had initial momentum of –14 kg · m/s; therefore, its velocity must have been ? m/s snowball b had initial momentum of 15 kg ∙ m/s, and a velocity of 5 m/s; therefore, its mass must have been ? kg. recognizing that momentum is conserved in inelastic collisions, the total momentum of the combined snowballs after the collision must be ? kg · m/s.

Some material consisting of a collection of microscopic objects is kept at a high temperature. a photon detector capable of detecting photon energies from infrared through ultraviolet observes photons emitted with energies of 0.3 ev, 0.5 ev, 0.8 ev, 2.0ev, 2.5ev, and 2.8ev. these are the only photon energies observed. (a) draw and label a possible energy-level diagram for one of the microscopic objects, which has four bound states. on the diagram, indicate the transitions corresponding to the emitted photons. explain briefly. (b) would a spring–mass model be a good model for these microscopic objects? why or why not? (c) the material is now cooled down to a very low temperature, and the photon detector stops detecting photon emissions. next, a beam of light with a continuous range of energies from infrared through ultraviolet shines on the material, and the photon detector observes the beam of light after it passes through the material. what photon energies in this beam of light are observed to be significantly reduced in intensity (“dark absorption lines”)? explain briefly.
