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.
