일반물리학 1 — Oscillations: Problem 53

53 An oscillator consists of a block attached to a spring (\(k = 425 \text{ N/m}\)). At some time \(t\), the position (measured from the system’s equilibrium location), velocity, and acceleration of the block are \(x = 0.100 \text{ m}\), \(v = -13.6 \text{ m/s}\), and \(a = -123 \text{ m/s}^2\). Calculate (a) the frequency of oscillation, (b) the mass of the block, and (c) the amplitude of the motion.
