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 150 m from the crossing
and its speed is 16 m/s.
If the engineerâ€™s reaction time is 0.75 s,
what should be the magnitude of the mini-
mum deceleration to avoid an accident?
