Question

a train starting from a railway station moving with uniform acceleration attains a speed of 40km per hour in 10 minutes. find its acceleration

Answer 1

v=u+at here u=0 as it starts from rest.
Now v=at or a=v/t
or,a=40*1000/(60*60*10*60) (converting both into second)
a=0.01metre per second squared....
