Astudent sits atop a platform a distance h above the ground. he throws a large firecracker horizontally with a speed v. however, a wind blowing parallel to the ground gives the firecracker a constant horizontal acceleration with magnitude a. as a result, the firecracker reaches the ground directly below the student. determine the height in terms of v, a, and g. ignore the effect of air resistance on the vertical motion.

Why do scientists believe that light is made of streams of particles? scientists believe that light is made of streams of particles because only the presence of photons can explain phenomena observed during experiments on the photoelectric effect. these observations include only some frequencies of light causing the ejection of electrons, no time gap existing between light striking a metal and electrons being ejected, and intensity having no effect on the kinetic energy of the ejected electrons.
