일반물리학 1 — Oscillations: Problem 48

48 The 0.800 kg cube in Fig. 15-37 has edge lengths \( d = 6.00 \text{ cm} \) and is mounted on an axle through its center. A spring (\( k = 3600 \text{ N/m} \)) connects the cube’s upper corner to a rigid wall. Initially the spring is at its rest length. If the cube is rotated \( 3^\circ \) and released, what is the period of the resulting SHM?
