Answer:
Displacement = 20
Direction = westward
Explanation:
Given that a football coach walks 18 meters westward, then 12 meterseastward, then 28 meters westward, and finally 14 meters
eastward.
To calculate the displacement,
Let eastward = negative
Westward = positive
Displacement = 18 - 12 + 28 - 14
Displacement = 46 - 26
displacement = 20 metre
Since the answer is positive, the direction is westward.
