When a 63 kg person climbs into a 1040 kg car, the car's springs compress vertically by 3.3 cm. What will be the frequency of vibration when the car hits a bump? Ignore damping.(adsbygoogle = window.adsbygoogle || []).push({});

Here is the FBD I have drawn:

Im not even sure if this is really right...

I really just don't know where to begin with this. I added the masses together...and I know I have an x value of 3.3 cm. I don't know how to conceptualize this so that the FBD makes sense...any tips or hints are appreciated
