Homework Help: One-dimensional impulse force

  1. Jan 22, 2009 #1
    1. The problem statement, all variables and given/known data

    A one-dimensional impulse force acts on a 3.0-kg object, as described in the graph below.

    http://qaboard.cramster.com/Answer-Board/Image/2006714849276328846376778312506582.jpg [Broken]

    Find:
    (a) The magnitude of the impulse given to the object.
    (b) The magnitude of the average force.
    (c) The final speed if the object had an initial speed of 6.0 m/s.


    2. Relevant equations

    F = (Po-P)/ (To-T)
    ???

    3. The attempt at a solution

    I have need some help here what my instructor has us read gives no help in solving 99% of our problems.


    Thanks

    For a graph of y vs x, if you find the area under that graph, you get what the product xy represents.

    ok so would (b) be
    (f+fo)/2
    (900+0)/2
    450N
