Homework Help: physics

Posted by bryan on Sunday, October 3, 2010 at 8:14pm.

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?
