Answer:30.50 m
Explanation:
Given
coefficient of friction between railroad and crates 
Train initial velocity (u)
To get the shortest distance brakes applied should be order of friction force between crates and railroad floor

using 
where v=final velocity
u=initial velocity
a=acceleration or deceleration
s=distance
here v=0 , u=16.94 m/s


s=30.502 m
