A train is traveling with a velocity of 72 km/h. The breaks are applied to retard the motion of the train uniformly. If the train stops after traveling 50 meters away from the place where the breaks were applied, find the retardation of the train.
A car starts from rest and accelerates uniformly at the rate of 1 m/s^2 for 5 seconds. It then maintains constant velocity for 30 seconds. Then breaks are applied and the car is uniformly retarded to rest in 10 seconds. Find the maximum velocity attained by the car. Also find the distance traveled by the car.
