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.

Open in App
Solution

Initial velocity of the train, u = 0 (since the train is initially at rest)

Final velocity of the train, v = 40 km/h

Time taken, t = 10 min = 10 × 60 = 600 s

Hence, the acceleration of the train is 0.0185 m/s2.
