Howitzer and Tunnel on Incline

Similar to the normal Howitzer and Tunnel, this demo involves a cart on an inclined track with a gun that fires a ball vertically. As the cart moves along the incline, the ball is launched straight up and, due to the combined effects of the cart's motion and gravity, follows a parabolic path. The ball lands back in the cart, demonstrating the principles of projectile motion and the effect of inclines on motion. This demo shows the independence of vertical and horizontal components of motion even when the cart is on an incline. However, when the howitzer is accelerated by a falling mass, pulley, and string, the ball does not fall back into the howitzer.
