Ballistic Pendulum and Projectile Lab

  1. May 11, 2010 #1
    1. The problem statement, all variables and given/known data
    I did a lab in physics where we used a ballistic pendulum. Basically we had to derive equations for the initial speed of the ball for the pendulum and as a projectile using energy/momentum and kinematics. I was just wondering what are some good sources of error for projectiles and pendulums?

    2. Relevant equations

    3. The attempt at a solution
    I thought of friction with the pendulum; because we ignored it when using the conservation energy. And for the projectile, air resistence. Any more would be a great help. Thanks
