The problem is from fundamentals of physics 9th edition by halliday.
Here is a free download of the book since I couldn't post the graph (I had to write out link since site doesn't allow links to be posted):

I am having trouble figuring out ch. 2 problem 82 (similar problem). My question is:
Figure 2-41
gives the acceleration a versus time t for a particle moving along an x axis. The a-axis scale is set by as = 13.0 m/s2. At t = -2.0 s, the particle's velocity is 10.0 m/s. What is its velocity at t = 6.0 s?
Note: Where it states as = 13.0, the s is supposed to be subscript.
The answer is 44.7, but I can't figure out how to get the same answer.

Figure the area under the acceleration-time plot. Just figure the area under the curve from t=-2 to t=6, then add the initial velocity at t=-2 of 10m/s, and you have it.
