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

SUMMARY
The conservation of momentum states that the total momentum of a closed system remains constant before and after a collision. The equation used to calculate this is Mass 1 x Vi 1 + Mass 2 x Vi 2 = Mass 1 x Vf 1 + Mass 2 x Vf 2. In the discussion, it is noted that if Mass 1 equals Mass 2 and Vi 1 is 4 m/s, this information can be directly applied to solve momentum-related problems. Participants are encouraged to share specific problems for further assistance.
PREREQUISITES- Understanding of basic physics concepts, particularly momentum.
- Familiarity with algebraic equations and variables.
- Knowledge of the terms "initial velocity" (Vi) and "final velocity" (Vf).
- Ability to apply conservation laws in physics problems.
- Study the principles of elastic and inelastic collisions.
- Learn how to apply conservation of momentum in two-dimensional collisions.
- Explore real-world applications of momentum conservation in sports and vehicle collisions.
- Investigate the relationship between momentum and kinetic energy in different types of collisions.
Students of physics, educators teaching mechanics, and anyone interested in understanding the principles of momentum conservation in various physical scenarios.

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. 
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.
