<u>Answer:</u>
<em>The initial distance between the trains is 1450 m. </em>
<u>Explanation:</u>
In the question two trains are of equal length 400 m and moves at a uniform speed of 72 km/h. train A is moving ahead of train B. If the train B has to overtake train A it should accelerate.
Train B’s acceleration is and it accelerated for 50 seconds.
<em></em>
<em>t=50 s </em>
<em>initial speed u=72km/h </em>
<em>we have to convert this speed into m/s </em>
<em></em>
<em>Distance covered in accelerating phase </em>
<em></em>
<em>
</em>
If a train is just behind another, the distance covered by the train located behind during overtaking phase will be equal to the sum of the lengths of the trains.
<em>Here length of train A+length of train </em>
<em>Hence the initial distance between the trains = </em>
