diagram for demo

CURRENTLY UNAVAILABLE. Inelastic collisions: The Ballistic Pendulum. The Rifle is fired by burning a thread which limits a spring-operated trigger. There is no provision for quantitative measurement of the swing of the rifle. It will suffice to have several students estimate the swing. Instructions to Set-up Person: The rifle and wood block should hang reasonably level, and swing in the same plane. If you load the rifle before class, stick around and make sure that no one messes with the set-up. Check rifle aim before firing. Mass of rifle is about 2437 gm. Mass of the bullet is about 2 gm. Mass of the wood block is 2340 gm.
