Question: give answer 3 A B i Two blocks A and B have masses m and 2m, respectively, and are free to move on a horizontal

give answer

3 A B i Two blocks A and B have masses m and 2m, respectively, and are free to move on a horizontal surface with negligible friction, as shown in the figure. Block A is initially moving with speed v, toward Block B, which is at rest and has a spring attached to one side. Block A then makes contact with the spring, causing the spring to compress. After the spring reaches its maximum compression, the blocks move apart and Block A loses contact with the spring. What is the speed of the center of mass of the blocks- spring system after the blocks have separated
