A person walks down 50 m directly north stops and then travel 32 m directly south. What is the displacement
The displacement is the overall change in position or the straight line distance from the starting point to the ending point. To calculate the displacement, we need to find the vector sum of the individual movements.
Walking 50 m directly north is equivalent to a displacement vector of 50 m in the positive y-direction (upwards). Walking 32 m directly south is equivalent to a displacement vector of 32 m in the negative y-direction (downwards).
To find the final displacement, we subtract the second displacement vector from the first one:
Displacement = 50 m - 32 m
Displacement = 18 m
Therefore, the displacement is 18 m upwards (along the positive y-axis).
