    Find tangential velocity given radius and the coefficient of friction

    Thank you for all the replies. I realized the normal force (also the force making up the centripetal force) cannot simply be accounted for by (mg) but has to be calculated from the frictional forces opposing the force of gravity. This means that (Mu*Fn = mg) which gives Fn=(mg)/Mu; This can be...

    Find tangential velocity given radius and the coefficient of friction

    I have attempted to solve for the velocity by setting the centripetal force (mv2)/r to the normal force pointed to the center of rotation (mg). This approach seems to give the incorrect solution and I am unsure of my misunderstandings.
