Two blocks m_A = 1 kg and m_B = 1 kg are forced together, compressing a spring between them by a distance x = 2 m; (the force constant of the spring is k = 2 N/m) then the system is released from rest on a level, frictionless surface. The spring, which has negligible mass, is not fastened to either block and drops to the surface after it has expanded. What is the speed that block A acquired, VA? O 0.5 m/s O 2 m/s O 1.414 m/s O 0.2 m/s O 1 m/s
