Homework Statement
For a certain oscillator the net force on the body with mass m is given by fx = -cx^3.
One-quarter of a period is the time for the body to move from x=0 to x=A. Calculate this time and hence the period.
Express your answer in terms of the variables A, m, and c.
Homework Equations
Ux = (cx^4)/4 < Calculated from previous question part
T=2 pi sqrt(m/k)
The Attempt at a Solution
I have got using the T equation, as far as:
= 8 pi sqrt (m/something)
but I am not quite sure what he something is.
Any ideas?
