At its highest point.
The ball has the highest potential energy at its maximum height (15m in the air). At the beginning, the ball has only kinetic energy and no potential energy. But as the ball travels upward, kinetic energy is converted into potential energy. When the ball changes direction, there is no kinetic energy, as all of it is now potential energy. As the ball returns back down, potential energy is converted back into kinetic energy.
Potential Energy - Stored Energy or the potential to do work Kinetic energy is energy of motion, as you in a car. If the car runs into a tree, the kinetic ehergy in your body throws you into the windshield. And it hurts.
The Ball has energy in the form of potential energy as if it was released it would fall to the ground. The pitcher uses chemical energy to move his arm and give momentum to the ball. The ball's energy is now transformed to kinetic energy as it moves through the air.
The velocity of the ball is 12 Meters per Second minus whatever velocity is lost due to the resistance of air while going up and coming back down (the loss is negligible for this example). As the ball leaves the student's hand it has a certain energy due to motion (Kinetic Energy). This energy is decreased as the ball rises and slows down. The energy is not lost. It is changing to energy due to position (Potential Energy). At the very top of the rise of the ball, where it stops, it has exactly the same Potential Energy as it had Kinetic Energy when it left his hand. It will start back down, losing Potential Energy and gaining Kinetic Energy on the way. When the student catches it it will have exactly the same Kinetic Energy it had when it left his hand on the way up. A very small portion of the energy is converted to the energy in heat due the air friction. In it's total travel absolutely no energy is lost.

The kinetic energy comes from potential energy, which he got from ATP energy, which is produced through food. Potential energy is converted to kinetic energy after the muscles contract and relax. Sources: School science

Depends what height it falls from or how hard Vinny throws it.

In a standard 10 frame game, you get two throws per frame for frames 1 to 9. In the tenth frame, you get two throws plus a bonus throw for a total of three. The minimum number of throws would be 12, this would be in a perfect game (a 300 game). The maximum number of throws would be 21.
1) To have a height advantage in catching "throws" and 2) To be able to see the parades better as the crowds form.
