## Homework Statement

Assume a particle of mass m which is free to move on the plane x-y. The particle is

experiencing a force F = −kr towards the origin. Find the equation y = y(x) that

describes the motion of this particle on the plane.

## Homework Equations

F = ma = -kr

r(t) = A[tex]_{1}[/tex]cos(wt)

**i**+ A[tex]_{2}[/tex]cos(wt)

**j**

The 'i' and 'j' above should be unit vectors in the x and y direction, respectively.

## The Attempt at a Solution

I think I'm supposed to use the r(t) formula above to isolate x, then substitute it back into the equation to get y?
