A train starting from a railway station and moving with uniform acceleration attains a speed of 40 km h-1 in 10 minutes. Find its acceleration.


Initial speed, u = 0 (As it starts from rest)

Final speed, v = 40 km/h


=


= 11.11 m/s


And,


Time taken, t = 10 minutes


= 10 × 60 seconds


= 600 s


Now,


Acceleration, a =


a =


a =


a = 0.0185 m/s2


= 1.85 × 10-2 ms-2)
