I’m trying to calculate how hard someone throws a ball. I know that F=ma, but the only force acting on a ball is the force of gravity and so the equation simply cancels out.

You might want to rethink that.

At the start of the throw the ball held in your hand is static . At the end of the throw when the ball leaves your hand it is moving . What has happened to the ball during this time ?
