Question

A 90-g bead is attached to the end of a 60-cm length of massless string. The other end of the string is held at point O, which is 200 cm above the floor, and the bead is swung counterclockwise at a constant speed in a vertical circle. The tension in the string when the bead is at the very bottom of the circle is 2.2 N. While the bead is in motion, a very sharp knife is inserted to cut the string directly below point O. How far to the right of the center of the circle does the bead hit the floor?
