일반물리학 1 — Oscillations: Problem 56

56 A particle with a mass of \(3.00 \times 10^{-20} \text{ kg}\) is oscillating with simple harmonic motion with a period of \(2.00 \times 10^{-5} \text{ s}\) and a maximum speed of \(1.00 \times 10^3 \text{ m/s}\). Calculate (a) the angular frequency and (b) the maximum displacement of the particle.
