a skydiver jumps out of a plane and eventually reaches terminal velocity. at different instances of the fall, a free-fall diagram of the forces acting on her is shown in the figure.
rank the diagrams in chronological order with the earliest diagram at the top of the list when the diver jumps off the plane.

Explanation:

1. When the skydiver first jumps, only downward force (gravity) acts; upward drag is 0, matching diagram D.
2. As speed increases, upward drag grows but is still smaller than gravity, so net force is downward, matching diagram C.
3. Speed keeps increasing, drag gets closer to gravity's magnitude, matching diagram A.
4. At terminal velocity, drag equals gravity, so forces balance, matching diagram B.

Answer:

1. D
2. C
3. A
4. B
