Answer:
calculating displacement.
Explanation:
It's not true that displacement and distance would be the same always. Displacement is always smaller than or equal to distance as it is the smallest path between the initial and final point whereas distance is the measure of the total path covered.
 
        
             
        
        
        
Answer:
Sum of the forces will be equal to 3.479 N 
Explanation:
We have given two same forces are oriented at an angle of 38°
Magnitude of each force is given 
We have to find the sum of the forces 
Sum of the forces will be equal to 

So sum of the forces will be equal to 
So sum of the force will be equal to 3.479 N
