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)
