→ The acceleration of the train - 8 m/s² since it is decelerating as the influence
of the brake comes to stop.
Q2. how long does it take the train to stop?
→ The average freight train is
about 1 to 1¼ miles in length (90 to 120 rail cars). When it's moving
at 55 miles an hour, it can take a mile or more to stop after the locomotive engineer fully applies the emergency brake. An 8-car passenger train moving at 80 miles an hour needs about a mile to stop.
