Homework Help: Spring compression

  1. Oct 12, 2006 #1
    i have a question in which a train collides with a buffer stop of mass 1.5 tons that asks how far the buffer stop is compressed. this is similar to a block and spring question, except the spring has mass. how is this included in the equation to solve for compression distance?

    Well, what do your conservation laws tell you? You know that momentum is conserved, and since there are no non-conservative forces at work, then energy will also be conserved.
