The Hardest Straight-In Pool Shot
When playing pool or billiards, a player often has the opportunity to make a "straight-in" shot, that is, one in which the cue ball, the object ball, and the target (e.g., a pocket) are collinear. With the distance from the cue ball to the target assumed fixed, the relative difficulty is here explored of shots taken at varying positions of the object ball between the cue ball and target. What position of the object ball makes the shot the most difficult? This is the question addressed in the article. Proofs of the results, ranging from easy to challenging, are left as exercises and also posted on the CMJ web site.
