Classical mechaincs problem (weird one)

  1. Dec 9, 2005 #1
    Hi,
    I've been given a homework question I don't even know what it means:
    A particle mass m travels in a one dimensional potential [tex]V=V_0 t g^2 (\alpha r)[/tex]. Find its period.
    This is the question exactly as it appears. Now, can t be time??? We haven't even touched time-dependent potentials (it's an undergraduate course).
    Also, is [tex]g^2[/tex] a function of [tex]\alpha r[/tex]? and what does [tex]\alpha r[/tex] mean? (my guess is distance from the center*constant).

    Most of our homework questions are taken (with some variation) from either Goldstein's Mechanics book or the Landau-Lif****z one [COME ON!!!! THE BOOK'S NAME IS LANDAU-LIFSHI&Z (&=T)], but in neither could I locate any question similar to that. Can anyone help?

    Thanks in advance.

    Well it appears that "tg" is actually the tangent function - Those idiots (can I say idiots?) used italic script so I was certain they ment 't' and 'g' as variables. Beside no one uses "tg" as tangent in printed/electronic media

    So do you still need help?
