A train start from rest and accelerate 100m/min sqare for 10 min . find the velocity accqired by the train . Train then runs with constant velocity for 20 min.the brakes are appplied then and train comes to rest with uniform retardation in 5min. Draw a velocity time graph and use it to find out the rate of retardation , total distance travelled and the average velocity of the train.

Taking
Acceleration (a) = 100 m/min2
t1 = 10 min
As the train starts from rest, u = 0
