Two train cars are connected as they move down the track. Which of the following are true comparing • the velocities of the two cars to one another over time, and • the accelerations of the two cars to one another over time? The cars' velocities are always identical to one another, but the accelerations of the two cars may differ from one another. O The cars' velocities are always identical to one another, and the accelerations are always identical to one another. O The cars' velocities may differ from one another, but the accelerations of the two cars are always identical. The cars' velocities may differ from one another, and the accelerations of the two cars may differ from one another.
