Description:

The SENCO 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

Setup:

1. Set up the bridge, the hose and the lead bricks in such a way that the cart does not roll off the table after it goes under the bridge. Make sure the open side of the bridge is the right distance from the edge of the table so that the trigger string is released right before the ball goes under the bridge.
2. Clamp the string to the lab bench.
3. Load the ball into the launcher by pressing it down and placing the pin in the whole.

Cautions, Warnings, or Safety Concerns:

1. The lead blocks weigh about 32lbs. Take care no to drop them or strain yourself.
2. Don't let the cart fall off of the lab bench; it is heavy.

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.
