/sci/ - Science & Math

I know this be taken as a homework request, but it isn't really

I'm 38 now, I haven't done any math since I left highschool, and I don't remember anything, I've been working in IT most of my adult life, and never used any math skills. Now I've signed up for an electronics course, and it is asking me a question like this for basic math review,

>For the object with zero initial velocity, suppose its acceleration is illustrated in the figure. Its velocity v(3s) = _ m/s

Now, can someone point me to what I need to learn in order to solve this? I don't want you to solve it, but if you could explain what kind of question this is and perhaps the relevant syllabus on khan academy or similar I'd be quite grateful.
