Answer:
Magnitude = 18 m
Direction = southward
Explanation:
Given that a tennis ball moves 18 meters northward, then 22 meterssouthward, then 14 meters northward, and finally 28 meters
southward.
To calculate the displacement, let the
Northward = positive direction
Southward = negative direction
Displacement = 18 – 22 + 14 – 28
Displacement = 32 – 50
Displacement = – 18
Since the answer is negative,
The magnitude will be 18 m and direction of the displacement is southward
