How do I solve problems involving conservation of momentum?

AI Thread Summary
To solve problems involving conservation of momentum, it's essential to understand that the total initial momentum of a system must equal the total final momentum. This can be expressed mathematically as the sum of the products of mass and velocity for all objects before the event equaling the sum after the event. When setting up a problem, identify all objects involved and their respective masses and velocities. Use the equation (massA)(velocityA) + (massB)(velocityB) = (massA)(velocityA) + (massB)(velocityB) to solve for unknowns. Mastering this concept is crucial for accurately analyzing momentum-related problems.

What's your problem? Does this have to do with the conservation of momentum?
 
Conservation of Momentum. Initial momentum must equal final momentum. Therefore...

(mass)x(velocity) = (mass)x(velocity)

or...

(massA)x(velocityA) + (massB)x(velocityB) ... (massX)x(velocityX) =
(massA)x(velocityA) + (massB)x(velocityB) ... (massX)x(velocityX)
 
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
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}...
