An engineer in a locomotive sees a car stuck on the track at a railroad crossing in front of the train. When the engineer first sees the car, the locomotive is 130 m from the crossing and its speed is 17 m/s.

If the engineer's reaction time is 0.36 s, what should be the magnitude of the minimum deceleration to avoid an accident?
Answer in units of m/s^2
