    You should have a textbook with this simple formula:

    F(centripetal) = M V^2/R

    Trying reading the assignment. It's a better way to learn than dumping off your questions here with multiple names.

    Perhaps it is different names, but the questions are remarkably similar. Having answered one, I thing WLS has answered them all. Acentripetal = v^2/r

  • Physics -

    Fc=(mv^2)/r
    (2.0*3.0^2)/0.5
