Objective : In this lab, we used a ballistic pendulum to measure the speed of a projectile fired using force from a spring. By using three different methods to determine the speed of the ball, our objective was to prove that our theoretical values for the speed of the projectile corresponded to the experiment values. Description : In this experiment we used a ballistic pendulum (pictured below). The projectile that we used was a small metal ball. We also used a meter stick and rulers to measure the distances. Theory : For the first part of the experiment, we are measuring the distance of the metal ball when propelled from the ballistic pendulum. This is a simple projectile motion calculation and v can be found using some manipulation of kinematics. In the second part of the experiment we used the law of conversation of momentum, along with the equations for kinetic and gravitational potential energy. When we manipulate and arrange
