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 330 m from the crossing and its speed is 21 m/s. If the engineer's reaction time is 0.44 s. what should be the magnitude of the mini- mum deceleration to avoid an accident? Answer in units of m/s2.
