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
