Calculating Impulse Based off a graph

  1. Oct 21, 2012 #1
    1. The problem statement, all variables and given/known data

    What is the impulse on a 3.0 particle that experiences the force shown in the figure (Figure 1) ?
    Figure 1:

    2. Relevant equations
    Impulse equations, force equations, how they relate.


    3. The attempt at a solution
    I added the area above the x-axis for the time interval 2 to 8 and subtracted the areas from 0 to 2 and 8 to 10. This answer came out to be 5000 N s which is incorrect. I'm confused because I thought the integral of force (the area bounded by the force graph) is equal to impulse.

    Help would be greatly appreciated. :smile:

    Your result seems too large. s vs ms, perhaps?

    Yes! I can't believe I didn't think of that. Thank you!
