Figure 13.1 8) In Fig. 13.1, two masses, M = 10 kg and m = 8 kg, are attached to a spring of spring constant 100 N/m. The system is set into oscillation with an amplitude of 58 cm. At the instant when the acceleration is at maximum, the 10 - kg mass separates from the 8 - kg mass, which then remains
