Homework Help: Acceleration v Time graph

  1. Oct 10, 2008 #1
    1. The problem statement, all variables and given/known data

    The problem is, to find velocity at a given time (t=5 sec) on a acceleration v time graph.

    2. Relevant equations



    3. The attempt at a solution
    I think the area under the curve represents the average velocity, but I really do not know how to find the velocity at THAT given time.

    *Note: I included a picture on the bottom, I tried to find the area under the curve but did not come up with the correct answer. It is the graph labled Particle C

    area under the curve is the velocity.

    You either

    1. Integrate acceleration up to t=5 if acceleration is given as a function of t OR

    2. Find the area under the curve within t=0 and t=5 inclusive
