Maurice Posted November 4, 2014 Share Posted November 4, 2014 Hello, Can somebody help me... A mass m is attached vertically to 2 springs, one spring at the ceiling K1 and the other one on the floor K2. What is the normal mode angular frequency for vertical motion? I found sqrt(5*k/m) but it don't seem good... Thanks. Link to comment Share on other sites More sharing options...
swansont Posted November 4, 2014 Share Posted November 4, 2014 What did you do to get the answer you posted? We have to see the work to figure out where you went wrong. Link to comment Share on other sites More sharing options...
elfmotat Posted November 4, 2014 Share Posted November 4, 2014 Do you know the position-space equations of motion for the mass? Do you know how to find them? What are your thoughts from here? Link to comment Share on other sites More sharing options...
JonathanApps Posted November 5, 2014 Share Posted November 5, 2014 What's k? You have K1 and K2 in the original question? Do we include the effect of gravity? Link to comment Share on other sites More sharing options...

Nor is your rephrasing a valid description of your attempts so far. @JonathanApps, K1 & K2 are the spring constants for the two springs involved.
