Find the lowest energy level for a particle in a box if the particle is a billiard ball (m=0.200 kg) and the box has a width of 1.5 m, the size of a billiard table. (assume that the billiard ball slides without friction rather than rolls. that is, ignore the rotational kinetic energy.)

since the energy in part (a) is all kinetic, to what speed does this correspond?

how much time would it take at this speed for the ball to move from one side of the table to the other?

what is the difference in energy between the n = 2 and n = 1 levels?

are quantum-mechanical effects important for the game of billiards?

Bernie drove home from a vacation in 1.5 hours. he traveled a total distance of 60 miles. what was his average speed in miles per hour? a. 60 mph b. 90 mph c. 40 mph d. 55mph

Glass is transparent to visibile light under normal conditions; however, at extremely high intensities, glass will absorb most of the light incident upon it. this works through a process known as multiphoton absorption. in this process, several photons are absorbed at the same time. if very intense light whose photons carry 2ev of energy is shined onto a material with a band gap of 4ev, that light can be absorbed through two-photon absorption, because two photons have the right amount of energy to bridge the band gap. what is the minimum number of photons of 800-nm light that are needed to equal or exceed the band gap of fused silica glass

Consider a system with two masses that are moving away from each other. why will the kinetic energy differ if the frame of reference is a stationary observer or one of the masses?
