"It's simple physics. Calculate the velocity V in relation to the trajectory T in which G gravity, of course, remains a constant."
You just figured it out. All the balls weigh the same. They are launched from a stationary position. The machine is calibrated to deliver the same speed until it is changed,
Get comfortable with a slower velocity and then increase. When you’re comfortable, increase again.
Batting is 60 percent technique and 40 percent fear. When you remove fear from the equation through mechanization, you can perform much, much better.
