A 0.2-kilogram disk sliding at 8 meters per second on a table with negligible friction, as shown, strikes a 1.0-kilogram disk sliding at 2 meters per second in the same direction. After the collision, the 0.2-kilogram disk slides backward at 2 meters per second. What is the speed of the 1.0-kilogram disk after the collision?
