Aspeed trap is set up with two pressure-activated
stripsplaced across a highway, 110 m apart. a car is speeding
alongat 33m/s, while the speed limit is 21 m/s. at the instant
thecar activates the first strip, the driver begins slowingdown.
what minimum deceleration is needed in order that theaverage speed
is within the limit by the time the car crosses thesecond
marker?

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 springâmass 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 (âdark absorption linesâ)? explain briefly.
