Chapter , Problem 18(choose chapter or problem)
As the drawing illustrates, two disks with masses m1 and m2 are moving horizontally to the right at a speed of v0. They are on an air-hockey table, which supports them with an essentially frictionless cushion of air. They move as a unit, with a compressed spring between them, which has a negligible mass. Then the spring is released and allowed to push the disks outward. Consider the situation where disk 1 comes to a momentary halt shortly after the spring is released. Assuming that m1 5 1.2 kg, m2 5 2.4 kg, and v0 5 15.0 m/s, fi nd the velocity of disk 2 at that moment.
