Question

mackinzie walks 4 blocks west, then 2 blocks south, then 4 blocks east, and, finally, 1 block south. what is the magnitude of her total displacement (in blocks)?

Answer 1

the magnitude of her total displacement in blocks is 3.

Answer 2

Answer:

3 blocks towards south        

Explanation:

Displacement is the shortest distance between the final position and initial position.

Initially mackinzie moves 4 blocks west, then 2 blocks south, the 4 blocks east and then 1 block south. Net displacement in East-west direction = 4 - 4 = 0.

In North South direction, net displacement = 2+1 = 3 blocks towards south
