Object 1 has a mass of 3 kilograms and moves across a frictionless surface at a velocity of 4 meters per second. Object 1 then strikes object 2, which has a mass of 2 kilograms and was motionless prior to the collision. The collision is completely inelastic. Providing your answer as a decimal to the nearest tenth, what is the speed of object 2 after the collision, in meters per second?
