As two trains move along a track, their conductors suddenly notice that they are headed toward each other. The figure gives their velocities v as a function of time t as the conductors slow the trains. The figure's vertical scaling is set by vs = 29.0 m/s. The slowing processes begin when the trains are 191 m apart. What is their when both trains have stopped?
