Final answer:
The question is about vector addition in physics, where two vectors A and B are added using the head-to-tail method. The resultant vector R represents the total displacement after moving along A and then B.
Step-by-step explanation:
If A and B represent two legs of a walk, or in physics terms, two displacements, then the total displacement after completing both moves can be represented by another vector R. The person or object that has moved along vector A and then along vector B ends up at the tip of vector R, which is the result of adding vectors A and B together.
The process of vector addition in physics involves the head-to-tail method. To apply this method:
- Draw vector A on a graph.
- Starting at the head (the tip) of vector A, draw vector B.
- The resultant vector R is drawn from the tail of A to the head of B.
The vectors must be drawn to scale using a ruler and protractor to accurately determine the magnitude and direction of the resultant vector R. This method is particularly useful for representing and calculating movements in two dimensions.
