Your car is stuck in ruts in the snow. How could you use the principle of resonance to free it?

Question

I know this has something to do with mechanical resonance and natural frequency, but I'm not sure how it works.

Answer 1

Maybe, it means physically rocking the car. Push or move the car back as far as it will go, then forward then back and so on. But you can not fight the motion of the car, the rate at which you push is the rate at which the tires would slip up and down the snow/ice from the affects gravity. If you can match the frequency that that would happen you will eventually be at a resonance with that. This may result a sufficent enought amplitude (height of tire up slope of the spot its in) so that the tires will slide over and out ot the spot its in.
