Question

A train starting from a railway station and moving with uniform acceleration attains a speed of 40km/hr in 10min find its acceleration in m/s*

Answer 1

Answer:

Explanation:

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= ( v−u )/t

=(11.1−0 )/600

=0.0185 m/s
