A drive of a mail train travelling `108 kmh^(-1)` sees a passenger train which is 250 m ahead on the same tarck. The passenger train is travelling in the same direation as the mail train. The velocity of the passenger train is `36^(-1)` .the driver of the mail train immediatly applies the brakes so as to produces a constant deaceleration of `1ms^(-2)` wherease the passenger train continues with the constant speed (i) calculate and find wheater there will be a collision (ii) if the collision occcurs where will it take place ?

Answer

no collision occurs mail train stops 100 m short of the passenger train
