As shown in the figure below, cars #1 and #2 are sliding across a horizontal frictionless surface. [Diagram of two cars on a track, labeled m₁ and m₂, both moving to the right with velocities v₁i and v₂i respectively.] The cars are equipped with a coupling arrangement similar to the one on railroad cars. Car #1 overtakes car #2 and they have a totally inelastic collision and become coupled together. You know the mass of each car; m₁ = 13.0 kg and m₂ = 44.0 kg. In addition, you are provided with the following graph, which shows the momentum of car #1 before, during, and after the collision. [Graph] - **Vertical Axis (p in kg·m/s):** Represents momentum in kilogram meter per second. - **Horizontal Axis (t in s):** Represents time in seconds. - The graph starts at 100 kg·m/s, maintains a constant value, and then drops at a point to about 40 kg·m/s, where it remains constant afterward. Determine the velocity (in m/s) of car #2 before the collision. [Input Box for answer: 1.28]
