In Fig. 15-34, 2 blocks (m = 1.8 kg and M = 10 kg) and a spring (k = 200 N/m) are arranged on a horizontal, frictionless surface. The coefficient of static friction among the 2 blocks is 0.40. What amplitude of simple harmonic motion of the spring-blocks system puts the smaller block on the verge on slipping over the big block?
