Question

a train starts from rest from a station with acceleration 0.2 metre per second square on a straight track and then comes to rest after attaining maximum speed on another station due to retardation 0.4 metre per second square. what is the distance between two stations is the length of train is neglected. ​

Answer 1

let total time =T

acceleration= 0.2

retardation=0.4

maximum distance between

stations = (0.2×0.4×T^2)/(2×0.2+2×0.4)

=(T^2)/15
