## Homework Statement

There is a particle that moves in 1-dimension. mass is m, force on the object is given as a function of position(x), F

_{x}= -mω

^{2}x.(ω is constant) when t=0 particle has x

_{0}>0, and velocity is zero. find the particle's position as a function of time.

## Homework Equations

There is a given hint for the problem. Use z=Acosu conversion on this integral

## The Attempt at a Solution

What i did so far: I used Newton's second law so that i can find accerelation. Then i integrate accerelation function and find velocity function as a function of position. Lastly i integrate velocity function and i find x= x

_{0}-ω

^{2}x

^{3}/6. From there i can't do anything. I couldn't use motion equations because accerelation is not constant. And i couldn't find how to use this integral.
