Question

5. A train starts from rest and gains a speed of 25 m/s in 60 seconds. Then the train runs at constant speed for 120 s. Lastly the train stops in next 60 s. Find the total distance traveled by the train. Also calculate the average speed of the train.​

Answer 1

Answer:

So, total distance moved =900m+1800m=2700m. Maximum speed of the train=60m/s. Position of the train at half its maximum speed. Here, you need to note that first the train is accelerating to 60 m/s, and then it is decelerating to 0 m/s.
