## Homework Statement

Fx=-d

**V**/dt where V=-(

**V**oa

^{2})/(a

^{2}+x

^{2})

## Homework Equations

How to solve this equation?

## The Attempt at a Solution

Fx=ma =md

^{2}x/dt = -d

**V**/dt =-d-(

**V**oa

^{2})/(a

^{2}+x

^{2})/dt. If I differentiate -(

**V**oa

^{2})/(a

^{2}+x

^{2}) I get more complicated results which Im unable to solve. PLEASE HELP ME cause I studied how to solve second order differential equations but this look dufferent.
