A mass, \(m\), tied to the end of a string is swung horizontally on a frictionless surface in the counter-clockwise direction, exhibiting uniform circular motion as shown in Fig. 1.
When the string returns to parallel to the \(x\)-axis, it is cut in half by a very sharp knife. The subsequent motion of the mass is:
The mass will pull sharply to the left.
The mass will continue in the positive y direction.
The mass will stop.
The mass will continue around the circle.
The mass will be thrown out of the circle with components in the positive x and y directions.
