A train sta

Answer :

As, 1min = 60s

So, 2min = 2 × 60s = 120s


According to First equation of motion


v = u + at


20m/s = 0m/s + a(120s)


m/s2 = a


According to Third equation of motion


v2 = u2 + 2as


(20m/s)2 = (0m/s)2 + 2 × m/s2 × s


400 = s


s = 1200m


the distance travelled by the train is 1200 m.
