6. In the figure, two masses, M = 16 kg and m = 12.80 kg, are connected to a very light rigid bar and are attached to an ideal massless spring of spring constant 100 N/m. The system is set into oscillation with an amplitude of 78 cm. At the instant when the acceleration is at its maximum, the 16-kg mass separates from the 12.80-kg mass, which then remains attached to the spring and continues to oscillate. What will be the amplitude of oscillation of the 12.80-kg mass?
(A) 35 cm,
(B) 62 cm,
(C) 98 cm,
(D) 78 cm,
(E) 180 cm.
