Frequency of Oscillations of Two Joined Springs and Block of Mass 0.245 kg

[apchemstudent]

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?
