Question: A particle moves in a medium under the influence of a retarding force equal to mk(v3 + a2v), where k and a are constants. Show

A particle moves in a medium under the influence of a retarding force equal to mk(v3 + a2v), where k and a are constants. Show that for any value of the initial speed the particle will never move a distance greater that π/2ka and that the particle comes to rest only for t → ∞.
