A vertical spring-block system with a period of \(2.3 \mathrm{~s}\) and a mass of \(0.35 \mathrm{~kg}\) is released \(40 \mathrm{~mm}\) below its equilibrium position with an initial upward velocity of \(0.12 \mathrm{~m} / \mathrm{s}\). For this system, determine the (a) amplitude, (b) angular frequency \(\omega,(c)\) energy, (d) spring constant, (e) initial phase angle, and \((f)\) equation of motion.
