    Natural log of a variable times the variable

    so I've got this equation down to x*ln(2/x) = 5 Can someone show/point me to a page where I can see how to solve this. I am under the impression it requires some type of ratio computation. thanks!

    Two objects launched into the air by identical springs

    since the equation for the energy of a spring is .5kx^2 and doesn't involve mass, one could say the masses leave the springs with the same energy. and for part E the potential energies would be the same since kx^2 is directly proportional to mgh---increasing mass would only decrease height...
