1)a train starting from a railway station and moving with uniform acceleration attains a speed 40 km h¬1 in 10 mins. find its acceleration.

=0.0185 ms

−2

Explanation:

Here we have, initial velocity,v=40km/h=11.11m/s

Time t=10minutes=60×10=600secs

We know that v=u+at

⇒40 kmhr

−1

=0+a×10m

⇒11.11 ms

−1

=a×600secs

⇒

600

11.11

=0.0185 ms
