TL;DR Summary: Tasked to formulate an equation relating piezoelectric effect and seismic waves during earthquakes. Using magnitude and distance attenuation to calculate stress/strain on the piezo system from earthquake energy. Need help checking if the basis and idea are correct

Is this for schoolwork? What resources have you been reading to try to come up with this?
 
Yes it is, so far I have only done it in a purely logical manner

Okay, I'll move your thread to the schoolwork forums then.

That's probably not the best way to approach this. Try searching for scientific articles on the subject to see how others have approached the problem. You could do the search with Google Scholar to narrow the results to scientific articles.
 
Thread 'Variable mass system : water sprayed into a moving container'
Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
