Question
The figure shows a ball attached to one end of an ideal string of length L=1.1 m. The
string's other end is held fixed as the ball is given an initial speed vo from point A where
0 = 27° on a vertical circle. Find the smallest possible value of vo if the ball at point B is
traveling along a circular arc of radius L. Ignore friction and air resistance.
