Question

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.NCERT Class IXSciences - Main Course BookChapter 8. Motion

Answer 1

Initial velocity (u)=0
Final velocity (v) = 40km/h
=11.11m/s
Time (t) = 10 minute
=10×60
= 600s
Acceleration = (v-u)/t
= (11.11-0)/600
= 11.11/600
=0.0185
So the acceleration was 0.0185m/s^2.
