$\huge\frak\pink{Answer}$

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

Here we have,

Initial velocity, u = 0,

Final velocity, v = 40km/h = 11.11m/s

Time (t) = 10 minute = 60x10=600s

Acceleration (a) =?

ANSWER

Given: t=10 min=10×60=600s

Initial speed of train is given as: u=0 ms

−1

Final speed of train is given as: v=40 km h

−1

=

3600

40×1000

=11.1 ms

−1

Now acceleration is given by the relation:

a=

t

v−u

=

600

11.1−0

=0.0185 ms

−2
