AI Thread Summary
The discussion focuses on the formulas used to describe elastic and inelastic collisions. For elastic collisions, the formula m1v1 + m2v2 = m1v1f + m2v2f is highlighted. Inelastic collisions are less clearly defined, but the complete inelastic collision formula m1v1 + m2v2 = (m1+m2)v' is mentioned. Links to Wikipedia articles on elastic and inelastic collisions are provided for further reference. Understanding these formulas is essential for analyzing collision scenarios in physics.

What formulas are used for what?

Elastic collisions:
m1v1 + m2v2 = m1v1f + m2v2f

inelastic...
i uno this one =(

complete inelastic:
m1v1 +m2v2 = (m1+m2) v' ?

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}...
