I happen to know this exactly because during my electrical engineering studies I sweated my way through many an exam in the murderous "Technical Mechanics" course. And even many, many years later, holding a totally yellowed degree certificate in my trembling hands, I only needed a short refresher to derive the formulas for the ball position as a function of the starting point, the angle and the velocity of the launch, and the elapsed time.
