Q15 A train starts from rest and accelerates uniformly at a rate of 2m/s² for 10s. It then maintains a constant speed for 200s. The brakes are then applied and the train is uniformly retarded and comes to rest in 50s. Find: (i) the maximum velocity reached, (ii) the retardation in the last 50s, (iii) the total distance travelled, and (iv)the average velocity of the train
