Ballistic pendulum lab question: How was energy lost while using the ballistic pendu

  1. Oct 20, 2011 #1
    1. The problem statement, all variables and given/known data
    How was energy lost while using the ballistic pendulum?


    2. Relevant equations
    Initial KE= 1/2mb*Vb^2 = 0.929J
    Final Potential graviational = (m+M)gh= 0.198J
    Energy loss = 0.929J - 0.198J= 0.731J

    3. The attempt at a solution
    I think the answer is:
    energy lost dues to friction (air resistance) and waste heat while using the ballistic pendulum.

    is this correct? Please help? Thanks a lot in advance.

    What kind of collision occurs when the ball (projectile) collides with the pendulum?
