An object of mass 10 kg is released at point a, slides to the bottom of the 30o incline, then collides with a horizontal massless spring, compressing it a maximum distance of 0.75 m. the spring constant is 550 n/m, the height of the incline is 2.0 m, and the horizontal surface is frictionless. round all answers to one decimal place.

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

A100 kg running back runs at 5m/s into a stationary linebacker. it takes 0.5 for the running back to be completely stopped
