Homework Help: What force gives me this impulse?

  1. Feb 26, 2008 #1
    1. The problem statement, all variables and given/known data
    what value of Fmax gives an impulse of 5.6 N\s?

    Picture of graph below

    2. Relevant equations

    Jx=Integral from t initial to t final of Fx(t)dt

    ^px=Jx


    3. The attempt at a solution
    I started by setting 5.6 Ns equal to the integral of the area below the curve but I think I am missing a step. I dont fully understand how you would start a problem like this could someone help me to get on the right track, thanks.

    I think you are on the right track.

    You started correctly by setting:

    [tex]J_x=\int_{t_i}^{t_f}F_x(t)dt[/tex]

    HINT: Next, get the integral in terms of the area.
