The physics of baseball Baseball players know from experience that there is a ``sweet spot'' on a baseball bat, about 17cm from the end of the barrel, where the shock of impact with the ball, as felt by the hands, is minimized. https://www.education.com/.../article/the-physics-of-cheating-in-baseball /N 22 0 R The average hitter needs about 50 milliseconds to instinctively assess the speed and location of an incoming pitch.
