    1. The problem statement, all variables and given/known data
    L=18ft , theta-dot=8rpm or .83776 rad/s, omega = 1 rad/s, fi-0=70.5 and fi-1=24

    2. Relevant equations - 3D motion


    3. The attempt at a solution
    I have come up with a ton of different answet inbetween 12-18 ft/s^2. Non have been correct

    Why don't you show us some of your calculations? There may be a simple mistake located in there somewhere.

    I can upload them later but don't have my notes on me right now.

    I am stuck on what the 2nd div is for phi. The first goes to zero but the second I am not sure. That is the one that is messing me up in the equation.

    We can't help you unless you show us what you've done.

    I mean, I'm guessing that "2nd div" stands for second derivative.

    If you truly want help, then provide us with your work. Those are the rules in the HW Forums.
