as the train is moving at the speed of 60km/ph and it is in uniform motion ,
so, as it is going to stop at 2 stations in one hour ,
the distance between the two stations are 30km and It takes 30min to reach on each of them
Answer:
u = 60km/h
v = 0km/h
t = 1h
a = ?
s = ?
For the first part
[tex]a \: = \frac{v \: - \: u} {t} \: = \: \frac{60 - 0}{1} = 60km {h}^{ - 1} [/tex]
acceleration = 60km/h
For the second part
[tex]s \: = \: ut + \frac{1}{2} a {t}^{2} = 0 \times 1 + \frac{1}{2} \times 60 \times {1}^{2} = 30km[/tex]
s = 30kms
