AP physics review questions and answers Three arrows are shot horizontally. They have left the bow and are traveling parallel to the ground as shown in the figure. Air resistance is negligible. Rank in order, from largest to smallest, the magnitudes of the horizontal forces F 1 , F 2 , and F 3 acting on the arrows. Some may be equal. State your reasoning.
