    Velocity, Displacement

    I am stuck on this question, I'm supposed to integrate the velocity equation right? I got 6t^2 + C, is that right? I've attached the question as an image.

    v = e^{-2t} + 12t

    did you forget to integrate the first term of the velocity function?

    I didn't do anything ... I just pointed out the omission in your "solution".

    Are you saying that you do not know how to find the antiderivative of e^{-2t} ?

    for k a konstant ...

    \int e^{kt} \, dt = \frac{1}{k}e^{kt} + C
