I have taken Calculus before but unfortunately no equation is given so I have to do it the old way.
An object is at x = 0 at t = 0 and moves along the x axis according to the velocity-time graph shown below
I am asked to find the final position x of the object at t = 18s.
Here is my logic, but apparently the answer is wrong.
I find the area of each of the sections of the graph. If the graph is below the x axis it's area will be negative. I found the answer to be 97m. I got this from -44+-11+28.5+76+47.5. But this is wrong.
