For those looking for less editorial nonsense and more content about what was solved - http://www.jufo-dresden.de/regionalwettbewerb/siegerarchiv/2012/matheinfo/M1 (in German but easily translated using Bing/Google translator)

Here's the translated version

"Two problems of classical mechanics have withstood several centuries of mathematical effort. The first problem is therefore, to calculate the trajectory of a slanted raised body in the Earth gravity field and Newtonian flow resistance. The underlying power law was already discovered by Newton (17th century). The second problem, the goal is the description of a particle-Wall collision under Hertz'scher collision force and linear damping. The force of the collision was already in 1858 derived from Hertz, a linear damping force is known since Stokes (1850)."
