Homework Help: physics

when an object of mass M1 is hung on a vertical spring and set vertical simple harmonic motion, its frequency is 12 Hz. When another object of mass m2 is hung on the spring along with m1, the frequency of the motion is 4hz. Find the ratio m2/m1 of the masses.

Dont you have an equation of the period on a spring? Remember that period is 1/frequency.

I will be happy to check your thinking.

w^2 = k/m

w = 2 pi f
=6.285 X 12hz = 5688
m1 = 5688/k

following the same steps

m1 + m2 = 632/k

i am stuck...
