The next time you go out for tennis practice, or to play a match, you might want to consider checking the balls being used on courts adjacent to you, and then use a different number. That is the one single reason why tennis balls have numbers on them.he number on a tennis ball is meant to help you identify your ball. Kind of like personalizing the ball so it doesn t look like everyone else s. All tennis players have experienced their ball bouncing or rolling onto the next court.
A tennis ball weighs 57 grams. An arm weighs about 2000 grams (4.4 pounds). The average of these two weights is 2057/2 = 1028 grams, which is way too heavy for a racquet. The geometric mean gives a more sensible answer for racquet weight. Multiply the numbers together and you get 57 Ã 2000 = 114,000 square grams. Now take the square root of 114,000 which is 337.6 grams. That is the geometric mean, and it may be the ideal weight in terms of racquet power (assuming your arm weighs 2000 grams). A 337.6-gram racquet is 5.92 times heavier than a 57-gram tennis ball, and a 2000-gram arm is 5.92 times heavier than a 337.6-gram racquet. Example 2: A Baseball Bat.
