Bullet in block

  1. Feb 22, 2007 #1
    1. The problem statement, all variables and given/known data
    See link.


    2. Relevant equations

    Imp = integral F dt
    mv = momentum
    1/2 mv^2

    3. The attempt at a solution

    I drew to FBD's to find the impulses and such, but I just don't know what to do. I then tried to use impulse momentum combined with conservation of energy, but got the WRONG answer. I can take a picture of my work, but it'll mean nothing...

    I was interested in solving this problem, but it turned out to be trickier than I thought it was...maybe I suck? hehe

    anyways, google helped me find this:


    looks familiar doesn't it?

    how frustrating...somehow I overlooked the use of v = vo + a*t

    so simple when you get another perspective, sometimes you get tunnel vision and want to solve it your own way but there are better ways

    anyways blah...rambling
