일반물리학 1 — Oscillations: Problem 36

36 In Fig. 15-33, two blocks (\(m = 1.8 \text{ kg}\) and \(M = 5.0 \text{ kg}\)) and a spring (\(k = 200 \text{ N/m}\)) are arranged on a horizontal, frictionless surface. The coefficient of static friction between the two blocks is 0.40. What amplitude of simple harmonic motion of the spring–blocks system puts the smaller block on the verge of slipping over the larger block?
