Homework Help: Calculate Height Change Help Needed

  1. Feb 4, 2010 #1
    Calculate change in height?
    I am working on a ballistic pendulum physics labs. I am trying to find the change in y(height) and bullet velocity.

    I ran the lab and received the following results:
    t (at max height (.780)
    in y= -.984
    final y= -789
    x in= 1.452
    x final=2.371

    I have no idea how to calculate the height change.

    When posting homework questions, please use the template that PF provides. What do you know about the ballistic pendulum? Isn't there a write-up that comes with the lab experiment? What does it say? What equations re relevant to the situation?
