A train passes an observer standing on a platform. The first carriage of the train passes the observer in time `t_(1) = 1 s` and the second carriage in `t_(2) = 1.5s`. Find its acceleration assuming it to be constant. The length of each carriage is: l = 12 m.

A train moving with a constant acceleration crosses an observer standing on the platform. The first and the second compartments, each 15 m long cross the observer in 2s and 2.5 s, respectively. Find the velocity of the train when its first compartment just crosses the observer and also find its acceleration.

A train passes a platform 110 m long in 40 s and a boy standing on the platform in 30 s.The length of the train is

A train passes an electric pole in 10 seconds and a platform 120 m long in 18 seconds. Its length in metres is :

A train passes an electric pole in 10 sec and a platform 120 m long in 18 seconds its length in metres is:

A train passes a pole in 15 seconds and a plattorm 100m long in 25 seconds.Then find the length of the train.
