im so lost with this question, i have tried a lot and cannot solve it :
A particle of unit mass moves on a straight line under a force having potential energy V (x) =
x3=(x^4 + a^4) where and a are positive constants. Sketch the graph of V (x).
(a) Find the period of small oscillations about the position of stable equilibrium
(b) Suppose the particle passes the origin, moving in the positive x-direction with speed v[0]. Show
that the particle will subsequently pass the point x = a if and only if v^2[0] > =a. Find a further
condition on v^2[0] for the particle to subsequently pass the point x = -a
(square brackets represent a subscript)
Thansk in advance----aa.
