A train starting from a railway station and moving with uniform acceleration attains a speed 40 km h−1 in 10 minutes. Find its acceleration.
Initial velocity of the train, u= 0 (since the train is initially at rest)
Final velocity of the train, v= 40 km/h = 40 x 5/ 18 m/s = 11.11 m/s
Time taken, t = 10 min = 10 x 60 = 600 s
Hence, the acceleration of the train is 0.0185 m/s2.
