A particle of mass m moves on the x-axis under the influence of a forace of attraction towards the origin give by

[tex] F= \frac{-k}{x^2} i [/tex].

If the particle starts from rest at x=a prove that it will arrive at the origin in a time given by

[tex] \frac{1}{2}\pi a \sqrt{\frac{ma}{2k}} [/tex]

Our teacher explained it to me in class but unforutently he wasn't able to finish it. I was wondering if someone could step me through this proof please.
