An object attached to an ideal horizontal spring undergoes simple harmonic motion on a frictionless surface with a period of \(6.0\text{ s}\). At time \(t = 0\), the object is released from rest at position \(x = +0.40\text{ m}\), where \(x = 0\) is the equilibrium position. At what time \(t\) does the object first reach position \(x = +0.20\text{ m}\)?
