Two blocks A of mass mA and B of mass mB are connected to each other by a spring of length L, spring constant k, and negligible mass. The two blocks are released from rest on a smooth floor (negligible friction) when the spring is compressed by half of the springs’ length. The blocks move away from each other with speeds that can be related using the conservation of combined momentum of the two blocks. Which of the following best describes the relationship between the speeds of the two blocks?
