An automobile and train move together along

parallel paths at 31.6 m/s.

The automobile then undergoes a uniform

acceleration of −4 m/s2 because of a red light

and comes to rest. It remains at rest for 44 s,

then accelerates back to a speed of 31.6 m/s

at a rate of 2.22 m/s2.

How far behind the train is the automobile

when it reaches the speed of 31.6 m/s, as-

suming that the train speed has remained at

31.6 m/s?

Answer in units of m
