Homeplate
Baseball's homeplate fits that description
.5 seconds
3 tenths of a second
Tonight, Ellsbury of the Red Sox vs. the Yankees
60 feet 6 inches like the MLB
prolly about 3 seconds
Behind home plate is great. The closer down the better, but even if you're a level up in the stands, it's a great place to watch the game.
A2 + B2 = C2 would be 902 + 902 = 16,200. Square of 16,200 would be 127.28'
in little league the home plate is exactly 44.4832 ft on a baseball regulation mound without a mound it would be about 44.2 ft give or take an error by the people that constructed the field
The distance from homeplate to left field is different in every ball park but it is normally between 280ft and 340ft.
This is because the rules of baseball say the mound is a distance from homeplate that is less than halfway the distance between homeplate and 2nd base. The distance is the same between each base in order (the same from home to 1st, 1st to 2nd, 2nd to 3rd, 3rd to home.) This results in the distance between homeplate and 2nd equal to the distance between 1st and 3rd. If you draw a line between homeplate and 2nd, and a line between 1st and 3rd, the lines will intersect in the center of the baseball diamond. However, the center point will be behind the pitcher's mound. You can use the Pythagorean Theorem to prove the distance from the mound to home is less than the center point, but that is another question. (Hint: The distance squared from home to first plus the distance squared from first to second divided by 2).
