AI Thread Summary
The conservation of momentum states that the total momentum before a collision equals the total momentum after the collision. The relevant equation is Mass 1 x Vi 1 + Mass 2 x Vi 2 = Mass 1 x Vf 1 + Mass 2 x Vf 2. In the given example, Vi 1 is 4 m/s and both masses are equal. Participants are encouraged to share specific problems for further assistance. Understanding this principle is essential for solving momentum-related problems in physics.

What do I use when momentum is conserved? Please post.

Hey honey! Here is the equation you would use!

Mass 1 x's Vi 1 + Mass 2 x's Vi 2=mass 1 x's Vf 1 + mass 2 x's Vf 2

and you are given that Vi 1 is 4 m/s and the mass 1 is = to mass 2 so there u go babe:)

Debbie said it well. :smile: If you add up all the momentum of all the things moving before a collision, it must equal the momentum of all the things moving after the collision.

If you have a specific problem that you're having trouble with, go ahead and post it, along with your thoughts on how to solve it, and we'll help you get it done.

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}...

Thread 'Struggle to understand the concept of the question (ice cube in water optics question)'

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...
