Question

a train starting from Railway Station and moving with uniform acceleration, a speed 40km/h in 10 minutes. find its accelertion

Answer 1

If it attains speed 40km/h (= 200/18 m/s) in 10 minutes then..,
Acceleration = Change in velocity / time taken
= (200/18 m/s - 0) / (10 × 60 s)
= 0.0185 m/s²

Answer 2

friend see its very easy question

here final velocity ,v = 40km/ h
convert it into m/s by multiplying it by 5/18
u will get 200/18m/s

niw, use the Newton's equation of motion
v=u+at
200/18= 0+600a
a= 1/54m/sec^2
