Homework Help: Joined Springs

  1. Jan 8, 2006 #1
    Two springs with a spring constant of k = 6430 N/m are joined and connected to a block of mass 0.245 kg. The system is then set oscillating over a frictionless surface. What is the frequency of the oscillations?

    This is what I think is the correct approach to this question:

    since the springs are joined, the new spring now has a spring constant of 6430/2 = 3215 N/m.

    So f = sqrt(k/m)/2*pi

    = 18.23 Hz.

    Is this correct? Thanks.

    Are the springs joined in series, or in parallel?

    they are in series

    As well, how would some one solve a problem like this, if the springs were not identical?
