A train starts from rest at station A and accelerates uniformly at 3x m s-2 until it reaches a
speed of 30 m s-1
. For the next T seconds the train maintains this constant speed. The
train then retards uniformly at x m s-2 ,until it comes to rest at a station B. The distance
between the stations is 6 km and the time taken from A to B is 5 minutes.
Show that 40/x+ T= 300
i think i have to work out the distances or something but i dont even know where to start :/
any help would be very appreciated!
