# 2) [20 pts ] Consider the following system involving four masses (1 kg) each spinning around a ring that has negligible mass. Each mass is connected by a massless cord

of length 1 m to a massless ring, and in the initial state as shown each mass has a velocity vo (noted by arrows) of magnitude 1 m's and the ring is stationary.However, at the point shown, the cords connected to mass A and D are cut using a high powered laser in a way that exerts no external force on the system of particles C, D, and the ring. Here you can assume the cords slide on the ring without friction, and you can neglect any effect from other external forces, such as gravity. With this information, please find: (1) The center of mass velocity (vector) of the system containing masses B and C immediately after the cords attached to A and D are cut. (2) The final velocity (magnitudes) of masses B and C relative to G (center of mass) for the system shown.Note that in the final configuration, you measure that the velocities of B and C relative to G to have equal magnitudes. (Hint: angular momentum methods can be useful for this type of system).
