Answer:
v = 80.48 km/h.
Explanation:
We have,
Acceleration of a train is 2 km/h/s or 7200 km/h²
Initial velocity of a train is 20 km/h
It is required to find the velocity after 30 seconds or 0.0084 h
Let v is the final speed. Using equation of kinematics as :
So, the final speed of the train is 80.48 km/h.
