## Homework Statement

Two masses m1 and m2 are joined by a spring of spring constant k. Show that the frequency of vibration of these masses along the line connecting them is

ω = √[ k(m1 + m2) / (m1*m2) ]

(Hint: Center of mass remains at rest.)

## Homework Equations

f = w/2π

w = √(k/m)

F = -kx

a = - w

^{2}x

## The Attempt at a Solution

I tried finding the center of mass and using that as m, in ma = kx

I also tried manipulating the formula for acceleration, and plugging it into hooke's law, but that didn"t seem right either. I'm pretty lost to be honest.
