What is the resultant displacemant?
A. The difference between two vectors.
B. vector addition.
C. the shortest distance from start to finish.
D. the product of two vectors.
Since the resultant is the vector sum of two or more vectors, I believe resultant displacment is the shortest distance between two points. You could say that it could be from start to finish, I am not entirely sure. So...
C is the answer
Hope this helped ;P
