In case you can't read it: A 90g bead on a 60cm long string is swung in a vertical circle about a point 200cm above the floor. The tension in the string when the bead is at the very bottom of the circle is 5.9N. A very sharp knife is suddenly inserted, as shown in the figure, to cut the string directly below the point of support. How far to the right of the center of the circle does the ball hit the floor? I need a full explanation please!
