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 = v - u/t

a = 11.11 - 0/600

a = 11.11/600

a = 0.0185ms/²

= 1.85 x 10^-2ms^-2
