Answer: The train traveled 210 miles in 6 seconds of time duration.
Explanation:
The initial velocity of the train,u = 50 mile/s
Acceleration of the train ,a = [tex]-5.0 m/s^2[/tex]
Duration of time ,t = 6 seconds
Using second equation of motion :
[tex]s=ut+\frac{1}{2}at^2[/tex]
[tex]s=50 mile/s\times 6 s+\frac{1}{2}(-5.0 m/s^2)(6s)^2=210 miles[/tex]
The train traveled 210 miles in 6 seconds of time duration.
