Question

question is a train start from a station and moves with a constant acceleration for 2 min . if it covers a distance of 400 m in this period , find the acceleration

Answer 1

okay first of all convert all the information given to you in SI units
next,
use the kinematical equation
s=ut+(at^2)/2
where s is the displacement , u is the initial velocity , t is the time and a is the acceleration
here time=2min.=120 sec. , s=400m u=0 as the train has started from a station that means it was initially at rest
so you get a=1/18 m/s^2
i hope this helps you:)

Answer 2

yes it helps
