Answer:
Average velocity will be 58.181 m/sec
Explanation:
Distance between station A and station B = 1188 meters
As the train starts from station A its initial velocity u = 0 m/sec
Final velocity is when it reaches at station B is 20 m/sec
Acceleration
From first equation of motion
20 = 0+2.41×t
t = 8.298 sec
Now from station train began to deaccelerate and finaly stop so final velocity v = 0 m /sec
Initial velocity u = 20 m/sec
We know that v = u+at
Deacceleration
So 0 =20 -1.65×t
t = 12.12 sec
So total time = 8.298 + 12.12 = 20.419 sec
So average velocity
So average velocity will be 58.181 m/sec
