Question

A student leaves a physics classroom and walks 1 meters south

to go to a water fountain. The student then walks 6
meters north to get to her math class. What is the magnitude
and direction of the girl's total displacement from the physics
classroom to the math classroom? Remember to include
positive or negative signs to indicate direction.

Answer 1

5m North

Step-by-step explanation:

Displacement is the distance between an object's current vs starting position.

If we consider the starting position to be (0,0), we subtract 1 from the y-component to go south and add 6 to go north. We get a position of (0,5), or 5m north.
