A train accelerated from 10km/hr to 40km/hr in 2 minutes. How much distance does it cover in this period? Assume that the tracks are straight?

Respuesta :

Distance s=829.586 m
Explanation:
The initial velocity of the train is u=10 km/hr=
The final velocity of the train is v=40 km/hr=
The time taken by the train is t=2 min=120 sec
Let the distance traveled by the train during acceleration be s
The acceleration of the train is,

From the equation of motion
