Want to Know Your Ball Speed?
There is a formula to calculate a player's velocity:
1. Determine the elapsed time (in seconds, i.e. 2.52) from the moment of the player's release to the moment of impact on the pins.
2. Divide this number into 40.91 (i.e. 40.91/2.52 = 16.23 mph).
And there you go. This formula is more accurate than the speed recorded on the score monitor because it calculates the overall speed of a player's ball speed, not at the end of the delivery, where the ball has slowed up due to transition from skid to hook to roll.
