Question

A tennis ball moves 22 meters southward then 12 meters northward then 16 meters southward and finally 34 northward

Answer 1

The tennis ball ended 8 m north from the starting point.

Step-by-step explanation:

If we label North as positive and south as negative for axis of reference, then the tennis ball performed the following displacements (in units of meters):

- 22 m + 12 m - 16 m + 34 m = 8 m

Which means that it ended 8 m north from the starting point.
