## The driver of a train A travelling at a speed of 54 km/h applies brakes and the train retards uniformly. The train stops in 5 s. Another train B is travelling on the parallel track with a speed of 36 km/h. This driver also applies the brakes and the train retards uniformly. The train B stops in 10 s. Plot speed -time graph for both trains on the same graph. Also calculate the distance travelled by each train after the brakes were applied.
