Competition billiard balls and tables need to adhere to strict standards (see the Billiard Congress of America for standards in the United States). Specifically, billiard balls must weigh between 5.5 and 6 oz, and they must be 2.25\pm 0.005 in. in diameter.
Using the theory presented in this section, establish whether or not it is possible to have a moving ball A hit a stationary ball B so that A stops right after the impact, if A and B have the same diameter but not the same weight (since it appears possible to have a weight difference of up to 0.5 oz while staying within regulations). Assume that the COR e = 1.
