Answer 2

initial velocity of train across =0

final velocity of train = 40km/hr

to convert kilometre per hour into metre per second I have to multiply 5/ 18

so

final velocity of train= 40*5/18

time to reach journey = 10 minute = 10*60= 600s

we know that

a= (v - u)/t

a = 40*5/600*18

a =1/54m/s^2
