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) .
