Projectile Motion

The Apparatus consists of an air pump, with a pressure gauge, which is attached through a one-way valve to a pressure chamber. The chamber is connected to a electrical (solenoid) push button valve which leads to the exit tube. The angle can also be adjusted. As the air is pumped, the pressure in the container rises. When the push button valve is pressed, the air escapes through the exit tube taking the Nerf ball with it.
