Homework Help: Springs in Series

  1. Oct 17, 2006 #1
    I have this homework question which I don't understand how to do it.

    Since I am not homew right now, I can't post up the picture. I will explain what the picture looks like.

    Picture:

    ___ = Wall
    $ = Spring
    | = Connection
    (*) = mass
    ____________
    $ 2.8N/cm
    $ 6N/cm
    (*) 41

    So basically we have 2 springs with diffrent elasticities hanging from the wall. And below the springs is a mass with 41N.

    1. What distance will the spring of constant 2.8 N/cm stretch? Answer in units of cm.

    2. In the same series spring system, what distance will the spring of constant 6 N/cm stretch? Answer in units of cm.

    Assuming the springs are massless, how much weight must each spring support?

    Oh wait, I got the answer. I was doing the calcuations wrong. Instead of deviding 41N by the 2.8 N/cm, I was deviding .41 by 2.8. I was trying to convert 41N to cm or something like that. lol
