Homework Help: Physics

Posted by tim on Thursday, September 30, 2010 at 2:03am.

A bob of mass = 0.250 is suspended from a fixed point with a massless string of length = 23.0 . You will investigate the motion in which the string traces a conical surface with half-angle = 25.0.
What tangential speed must the bob have so that it moves in a horizontal circle with the string making an angle 25.0 with the vertical?

Im setting it up right but keep getting the wrong answer
