• 6.0 m/s

• 2.0 m/s

• 3.0 m/s

• 12 m/s

A 1.2-kilogram block and a 1.8-kilogram block are initially at rest on a frictionless, horizontal surface. When a compressed spring between the blocks is released, the 1.8-kilogram block moves to the right at 2.0 meters per second, as shown. What is the speed of the 1.2-kilogram block after the spring is released? [You MUST show all work in your notebook to receive full credit for this assignment!]
