Answer:
The distance is 
Explanation:
From the question we are told that
The coefficient of static friction is 
The initial speed of the train is 
For the crate not to slide the friction force must be equal to the force acting on the train i.e

The negative sign shows that the two forces are acting in opposite direction
=> 
=> 
=> 
=> 
From equation of motion

Here v = 0 m/s since it came to a stop
=> 
=> 
=> 
Option A is the correct answer.
The expression, in terms of defined quantities and g is therefore Fu =((mg/2) +2 mp) g
<h3>
What is a Scale?</h3>
This can be defined as a balance or any of various other instruments or devices for weighing.
The expression in terms of defined quantities and g, for the force that the scale under left pillar shows that Fu =((mg/2) +2 mp) g .
