Final answer:
The terms 'Fletching', 'Range', 'Rock', and 'Shaft' are most closely associated with Archery (A). Fletching and Shaft are components of an arrow, and Range refers to the practice area. Projectile motion in archery prefers flatter trajectories in windy conditions, while larger angles are for overcoming obstacles or for distance.
Step-by-step explanation:
The terms Fletching, Range, Rock, Shaft are associated with sport A) Archery. Fletching refers to the fin-shaped aerodynamic stabilization device attached to arrows or darts, 'Range' is a place designed for archery practice, 'Shaft' is the long, slender body of the arrow, and 'Rock' does not directly relate to archery, however, it could be a typo for 'nock', which is the slotted end of the arrow that holds the bowstring.
Regarding projectile motion in archery, for a fixed initial speed, the range of a projectile is determined by the angle at which it is fired. With two different angles potentially yielding the same range, the smaller angle is often preferred because it results in a flatter trajectory, reducing the effect of variables like wind on the arrow's flight. An archer might use a larger angle when they need to shoot over obstacles or at greater distances. Similarly, a punter in a football game uses a higher trajectory to ensure more hang time for the ball, allowing their teammates to get downfield to stop the return.
In the context of an archery competition, precision refers to how close together all the shots land (consistency), while accuracy refers to how close the shots land to the target's center. Precise archers have a tight grouping of arrows, whereas accurate archers are more likely to hit the intended target spot, regardless of grouping tightness.
