Answer:
The displacement is 5 meter.
Explanation:
As per the data given in the question we have to find the ruthie's displacement.
As per the question it is given that ruthie walks 45 m east, and then moves 40 m west. If east is chosen as the positive direction.
ruthie moves 45m east and then back towards original position so displacement is = 45 - 40 = 5 meter
As we know the displacement is as the change in position of an object. It is a vector quantity and has a direction and magnitude. It is represented as an arrow that points from the starting position to the final position.
Displacement Formula
Displacement = Final position – initial position = change in position
Hence, the displacement is 5 meter.
