# Two trains, a freight train and a commuter train, are traveling in the same direction on parallel tracks. At t = 0 s, the front of the freight train...

t

the front of the freight train is 88.0 m ahead of the front of the commuter train. Be consistent, and measure everything from the front of each train. The graph above shows the velocities of the two trains from t

to t

Note that both trains have a constant acceleration until t1

and then they both travel at constant velocity. Take v

20.0
