9.- Un cuerpo de masa 3 kg se hace subir por la acción de una fuerza vertical de 50 N. Calcula la aceleración del movimiento y el espacio que recorre después de cinco segundos. Si en ese instante cesa la fuerza, ¿qué espacio recorre desde ese instante hasta que se para y vuelve a caer?

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
