explanation:

v=uf/(u-f)

= 5.-10/(5+10) convex lens has negative focal length

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
