Mr. Poczekaj has determined the mass of a potato to be 0.163kg. He throws it at a wall with an acceleration of 28m/s². Does this potato have enough force to break if a potato requires 5 Newtons of force to break? *

Can someone explain to me how to do this problem ?

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
