A mass m = 2.4 kg is attached to two springs as it slides along a frictionless floor, while the springs are fastened to two walls as shown in Figure P11.17. The springs both have k = 400 N/m and are both in their relaxed states (un stretched and uncompressed) when the mass is centered between the two walls. What is the frequency of this simple harmonic oscillator?
