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: http://session.masteringphysics.com/problemAsset/1382988/2/09.EX04.jpg 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.
