I attempted the question 1-a of 2016 paper.It asked the minimum braking distance for passenger and freight train.Now passenger train and freight train runs at speed of 120Km/h with acceleration/de-acceleration of 0.8 m/s and 100 Km/Hr with ace./de-ace. rate of 0.5m/s.
After calculation they give me braking distance as follows:- passenger rains 695 meters and freight train 773 meters.
Do I need to consider 773 meter as D(distance between consecutive stop signal for my answer to question 1.b??
