124 Ballistic Pendulum — Part II Previously, we used a ballistic pendulum to measure the initial velocity of a projectile (steel ball) fired from a spring-loaded gun. Now we’ll test that result by predicting and then measuring the range of a ball fired from the gun. Equipment. Ballistic pendulum device. Make sure you use the same device that you used in Part I . Rule. Target box, carbon paper. Theory First make your prediction for L , given the muzzle velocity v 0 you determined earlier, using the ballistic pendulum. You should also work out a formula for the uncertainty in L . 1. Use your knowledge of projectile motion to find an equation for L in terms of ( H+h ), the initial height of the ball above the floor and the muzzle velocity v 0 . 2. Given estimated uncertainties Δ H , Δ h and Δ v 0 , find an equation for the uncertainty in L . When you have done this, have your work checked. If it looks good, you can go ahead and set up your equipment.
