Two trains travelling on the same track are approaching each other with the equal speed of 40 m/s. The drivers of the train begin to deaccelerate simultaneously when just 2.0 km apart. Assuming deacceleration to be uniform and equal, the value of the deacceleration to barely avoid collision should be?

We have,

Initial speed, u = 40 m/s

Distance to be covered by each train before rest, s = 1000 m

Acceleration, a = ?

Using the relation,

v2 = u2 + 2as
