Homework Help: Help interpreting a momentum graph

  1. Jan 3, 2010 #1
    1. The problem statement, all variables and given/known data

    What is the objects momentum at 3 seconds, on the graph at 3 seconds it is exerting 35n

    2. Relevant equations

    f=change in momentum/time

    3. The attempt at a solution
    I got 105kgms but it was marked wrong...
    I can make the graph in paint if it will help anybody.

    It would be beneficial to post the graph as well.

    then simply the area under the graph gives the change in momentum, so from t=1 to t=3 find the area. It forms a rectangle and triangle.
