Given data:
The initial velocity of the train is,
[tex]\begin{gathered} v_i=9\text{ miles/hour} \\ v_i=\frac{9}{2.237}\text{ m/s} \\ v_i=4.02\text{ m/s} \end{gathered}[/tex]
The final velocity of the train is,
[tex]undefined[/tex]
Solution:
The average acceleration of the train is,
[tex]a=\frac{v_f-v_i}{t}[/tex]
where v_f is the final velocity, v_i is the initial velocity, and t is the time taken,
Substituting the known values,
[tex]undefined[/tex]
