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 1000 / 60 x 60 = 11.1 m/s
Time taken, t = 10 min = 10 × 60 = 600 s
Now acceleration is given by the relation :
Hence, the acceleration of the train is 0.0185 m/s2.
