Homework Help: How to make physics problem obey momentum conservation?

  1. May 27, 2015 #1
    1. The problem statement, all variables and given/known data
    Can you change the system (as you would in a work/energy problem) so you can get rid of all external forces in a momentum problem for example by making your system the earth, a mass, and a spring (if the problem involved those 3 objects)?

    2. Relevant equations


    3. The attempt at a solution

    conceptual question

    Even with a conceptual question you still need to show your own effort.
