The Net Force Is 4
First, let's remember that you find the "Net Force" of an object by the direction its going. In this case, they are both pointing in different directions.
Next, we find the "Net Force" by subtracting them and the one with the biggest force, you go in that direction.
Finally, once we subtracted 5 from 9 we get a "Net Force" of 4

(I am pretty positive thats the answer)

The grasslands in these continents gave him a chance to notice that species do vary globally. He observed the similarities between the different large, flightless birds species–rheas, ostriches, and emu.
