Two trains, each with a speed of 50 kmph are headed towards each other on the same trake. A bird that can fly at the rate of 100kmph flies off one train when they are 100km apart and heads directly to the other train. On reaching the other train it flies back to the first train and so forth. (a) How many trips can the bird make from one train to the other before they crash ? (b) How is the total distance the bird travels ?

A train leaves station A at 9:20 am and reaches the station B at 1 : 30 pm. The time taken by the train is

Two stations A and B are 100km apart. A passenger train crosses station A travelling at a speed of 50 km//hr . The train maintains constant speed for 1 hour 48 minute and then the driven applies brakes to stop the train at station B in next 6 minute. Another express train starts from station B at the time the passenger train was crossing station A. The driver of the express train runs the train with uniform acceleration to attain a peak speed v_(0) . Immediately after the train attains the peak speed v_(0) , he applies breaks which cause the train to stop at station A at the same time the passenger train stops at B. Brakes in both the trains cause uniform retardation of same magnitude. Find the travel time of two trains and v_(0) .

Two trains are headed towaads each other on the same straight rrach, each vaving a speed of 30 km h^(-1) . A bird that can fly at 60 km h^(-1) flies off one train when they are 60 km apart and leads firectly form the otjer train, On reaching the other train, tg flies back to the first train and so on. (a) How many trips can the bird make from one trin to the other train befre they meet ? (b) What is the total distance the bird travels ?

While starting from a station, a train driver was instructed to stop his train after time T and to cover maximum possible distance in that time. (a) If the maximum acceleration and retardation for the train are both equal to ‘a’, find the maximum distance it can cover. (b) Will the train travel more distance if maximum acceleration is ‘a’ but the maximum retardation caused by the brakes is ‘2a’? Find this distance.
