Two trains, which are moving along different tracks in opposite directions, are put on the same track due to a mistake. Their drivers, on noticing the mistake, start slowing down the trains when they are 300 m apart. Graphs given below show their velocities as a function of time as they slow down. The separation between the trains, when both have stopped, is:
  • a)
    120 m
  • b)
    280 m
  • c)
    60 m
  • d)
    20 m
Correct answer is option 'D'. Can you explain this answer?

Two trains, which are moving along different tracks in opposite direct...
Initial distance between trains is 300 m. Displacement of 1st train is calculated by area under V-t.


Displacement of train Which means it moves towards left.
∴ Distance between the two is = 300 - 280 = 20 m
