    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
