Physics lab practical (Centripetal Force)

    physics lab practical!!! (Centripetal Force)

    1. The problem statement, all variables and given/known data
    I need help to come up with a lab to figure out the centripetal Force of a cork as it rolls down the ramp.


    2. Relevant equations
    Fc=(mv^2)/r


    3. The attempt at a solution
    i know that Fc= (mv^2)/r ,but i don't know if the velocity in the equation is the velocity of the cork rolling down the ramp or some other velocity

    Thank you.

    v for centripetal force refers to tangential velocity of the rolling object, so its the velocity of the cork rolling down the ramp, assuming the cork has enough friction against the ramp to not slide.
