Question

a train starts from rest and moves with a constant acceleration of 2 metre per second for half minute the place are there then applied and the train comes to rest in one minute (a).find the total distance moved by the train (b) .find
the maximum speed attained by the train​

Answer 1

Explanation:

we are given;

u= 0m/s

a= 2m/s²

t= 1 min. =60s

s=?

v=?

I) first we get the distance covered by the train

we know,

s=ut+1/2at²

s=0(60)+1/2(2)(60)²

s=60×60

s=3600 m

II) now we get the maximum velocity attained by train

we know,

v=u+at

=>v=0+2(60)

=>v=120

therefore maximum velocity attained by the train = 120m/s

Answer 2

Explanation:

here is your answer hope it helps you
