Question about something reaching exactly +

    [SOLVED] Question about something reaching exactly +

    1. The problem statement, all variables and given/known data
    Sorry, I accidentally hit the enter button. Anyways my question is about something reaching exactly +2G acceleration on a turn. I tried asking my friends and teacher about it but it didn't exactly make sense the way they explained it. I just want to know what that means to have a +2g acceleration when turning

    Tangential or normal? I think you'll have to explain more about what your friends and teachers explained and express that in the form of a question.

    I think normal.

    Normal (centripetal) acceleration is given by v^2/r, where r is the radius of the turn and v is the velocity. If that's equal to 2g, then 2g=v^2/r.

    Oh okay. That makes sense now. So that would mean that 2(-9.81m/s^2) = v^2/r right?

    Right. Except I wouldn't put a minus sign on g in this context. g is just a magnitude, not a direction.

    Oh okay. Thanks so much!
