A train 50 m long travels on a plain and level track and reached a post in 5 secs. Find (i) speed of the train (ii ) the time train will take to cross 450 m long bridge.

A train 120 m long moving on a straight and track with uniform speed passes a pole in 6 seconds Find: the speed of the train.

A 120 m long train is moving west at a speed of 10 m s^-1 .A small bird flying cast at a speed of 5 ms^-1 crosses the train.What is the time taken by the bird to cross the train?

A train passes over a 200 m long bridge in 10s. The length of the train is 100 m. The speed of the train is

A train 100 m long is moving with a velocity of 60 kmh^-1 . Find the time it takes to cross the bridge 1 km long.

Formulate the following problems as a pair of equations, and hence find their solutions. :- Roohi travels 300 km to her home partly by train and partly by bus. She takes 4 hours if she travels 60 km by train and the remaining by bus. If she travels 100 km by train and the remaining by bus,she takes 10minutes longer. Find the speed of the train and the bus separately

After covering a distance of 30 km with a uniform speed there is some defect in a train engine and, therefore, its speed is reduced to 4/5 of its original speed. Consequently, the train reaches its destination late by 45 minutes. Had it happened after covering 18 kilometres more, the train would have reached 9 minutes earlier. Find the speed of the train and the distance of journey.

The radius of curvature of a railway track at a place where the train is moving at a speed of 72 km h^-1 is 625 m.The distance between the rails is 1.5 m.Find the angle and the elevation of the outer rail so that there may be no side pressure on the rails. (g=9.8 m s^(-2)) .

A 130 m long train is moving in a direction with speed 20 ms^-1 . Another train moving with 30ms^-1 and 120 m long crosses the first train in a time

A train runs along an unbanked circular track of radius 30 m at a speed of 54 km//h . The mass of the train is 10^6 kg . What provides the centripetal force required for this purpose — Hie engine or the rails ? What is the angle of banking required to prevent wearing out of the rail ?

A person crosses a 600 m long street in 5 second. What is his speed ?
