Description:

The CENCO ballistic cart is equipped with a spring loaded vertical ball launcher. The launcher is fired when the pin is pulled out by a string.

Important Setup Notes:

1. This demonstration requires practice

2. Setup time is about 5 minutes
3. If the vertical alignment of barrow is off, the ball will not go back into the cup. Check the level of the table and if necessary there are 2 adjustment screws on the bottom of the cart that will help you to realign the barrow.

Setup:

1. Make sure that the lecture bench is level.
2. Clamp the C-clamp with string and trigger pin to one end of the lecture bench.
3. Set up the bridge. Make sure that the bridge is the right distance the cart with the trigger string fully extended. This distance is about 1 foot.
4. The hose is set out some distance from the bridge such that it stops the cart from roll off the table. The lead bricks are used to hold the hose.
5. Load the ball into the launcher by pressing it down all the way and placing the trigger pin in the second whole.

Cautions, Warnings, or Safety Concerns:

1. The lead blocks weigh about 32lbs. Take care not to drop them or strain yourself.
2. Don't let the cart fall off of the lecture bench; The alignment will get messed up.

Demonstration:

Give the cart a good push. It takes practice to get the right speed so that the ball is in the air when the cart is under the bridge. After you push it, the cart rolls at constant velocity. It launches the ball, goes under the bridge, and catches the ball. The ball goes over the bridge and the cart goes under. Because both the ball and the cart have constant velocity in the horizontal direction the ball will fall back into the launcher. Horizontal and vertical motion are independent.
