# How many rotations will a baseball turn when it is thrown as a fastball at 96 mph from 60 feet 6 inches?

I know the answer to this but I want to hear what you think it is.

A fastball can spin at a top speed of 1800 rpm and a 96 fastball takes about .4 seconds to get to the plate. Therefore it rotates about 12 times.

This is not a knowable answer.

The number of rotations a baseball will make is entirely dependent on the spin which is placed on it by the pitcher, regardless of the distance and speed supplied. One can assume that faster pitches generally will have a faster rotation, and will rotate more times over a longer distance, but you would need to know the rotational velocity of the baseball in order to answer this question.
