Question

6.In the figure, two masses, M and m in kg, are connected to a very light rigid bar and are attached to an ideal massless spring of spring constant k N/m. The system is set into oscillation with an amplitude of A1 cm. At the instant when the acceleration is at its maximum a1max, the outside mass M separates from m, which then remains attached to the spring and continues to oscillate. After separation, the oscillating system #2 consists of the spring and m. Before separation, the oscillating system #1 consists of both masses and the spring.

A) The maximum system velocities compare as: v1max < v2max

B)The maximum system spring potential energies compare as: U2max > U1max

C)The maximum system accelerations compare as: a2max > a1max

D) The system oscillating frequencies compare as: f2 > f1

E) The system oscillating amplitudes compare as:   A2 > A1

F) The maximum system kinetic energies compare as:   KE2max = KE1max

G)The system oscillating spring constants compare as: k2 > k1

H) a2max = (3/2) a2max
