i am confused on how to set up a problem involving initial and final momentum :yuck: . . . please help

 

[Jameson]

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)
