**drwls**, Sunday, June 6, 2010 at 12:07amLet T be the tension force in the string.

Apply vertical and horizontal force balances.

T cos 30 = weight = M g

T sin 30 = centripetal force = M V^2/R

Divide one equation by the other. This will eliminate the unknown T

tan 30 = V ^2/(Rg)

Solve for V

My answer was 16.8 m/s. Is that correct?
