Two masses, M=17 kg and m=10.2 kg , are attached to a spring of spring constant 100 N/m The system is set into oscillation with an amplitude of 7 cm.
At the instant when the acceleration is at maximum , the 17 kg mass separates from the 10.2 kg mass , which then remains attached to the spring and continues to oscillate. The amplitude of oscillation of the 10.2 kg mass will be:
