does this illustration show a sky diver at terminal velocity? explain your answer.

Brief Explanations:

Terminal velocity occurs when the force of gravity pulling the skydiver downwards is equal to the air - resistance pushing upwards, resulting in zero net force and constant velocity. In the illustration, if the arrows for gravity and air - resistance are of equal length, it implies equal forces and thus the skydiver is at terminal velocity. If not, the skydiver is accelerating or decelerating. Without knowing the relative magnitudes of the forces (lengths of the arrows in a more precise sense), we can't be certain. But if we assume the arrows represent equal forces, then yes.

Answer:

If the forces of gravity and air - resistance are equal (represented by equal - length arrows), then yes, the skydiver is at terminal velocity. Otherwise, no.
