clearly the net force is the sum of the downward and upward forces:
-1.5N + 0.7N = -0.8N
That is, 0.8N downward
You just added the magnitudes, but did not take into account the directions
A balloonist drops an apple weighing 1.5 N over the side of the balloon's gondola. As it falls and increases speed, the drag force from the air upward on it increases. When the upward force is 0.7 N, what is the direction and magnitude of the net force on the apple?
9.8 N downward
1.5 N downward
0.7 N upward
0.8 N downward
I got 2.2 N downward.. I don't understand what I did wrong, can you help me
