A train starts from a station P and travells to another station B at a distance of 5000m. `4m//s^(2)` is the acceleration with which it can acceleration and `8m//s^(2)` is the deceleration with which it can decelerate. For first 2000m there is a speed limit of 40 m/s and later speed limit is 20 m/s for next 2000 m and there is no speed limit for last 1000 m
`{:(" Column-I","Column-II"),("A) Total time for which it accelerates","P) "11.854 sec),("B) Total time for which it decelerates " ,"Q) "143.125 sec),("C) Total time for which it will be in uniform motion" ,"R) "178.68 sec),("D) The total time of journey is ","S) "23.7 sec),(,"T) "163.2 sec):}`
