Homework Help: Question about Applying V^2/r with two different velocities

    [SOLVED] Question about Applying V^2/r with two different velocities

    1. The problem statement, all variables and given/known data
    I have a problem where I am using the equation V^2/r = -1g to a problem with centripetal force. Basically the question is designing my own situation where i need to have a -1g acceleration on a turn and i decided on the picture below. It is a vertical picture.


    2. Relevant equations
    -1g = v^2/r

    3. The attempt at a solution

    I tried figuring out exactly how to get the velocity but I just don't seem to see which velocity to use.
