उत्तर
Suppose a train starts from rest and accelerates uniformly for some time and then moves with a constant velocity for a certain time interval. Then on applying the brakes, the train is uniformly retarded and comes to rest after some time in this situation, velocity – time graph of the train will be the same as shown in the figure.
