What is the magnitude of the final momentum of the system (all three pieces)?
What is the mass of the third piece?
What is the x-component of the velocity of the third piece?
So I don’t even know where to begin with this…
In class we went over Kinetic Energy of a system but not for momentum…Would it just be the sum of the masses times the sum of the velocities…? I don’t know m3 or v3 though 🙁
