A small 0.400-kg object moves on a frictionless horizontal table in a circular path of radius 3.30 m. The angular speed is 6.63 rad/s. The object is attached to a string of negligible mass that passes through a small hole in the table at the center of the circle. Someone under the table begins to pull the string downward to make the circle smaller. If the string will tolerate a tension of no more than 113N, what is the radius of the smallest possible circle on which the object can move?

A 250-g mass hangs from a string that is wrapped around a pulley, as shown in the figure. The pulley is suspended in such a way that it can rotate freely.

A weight of mass 1.32 kg is suspended by a string wrapped around a pulley wheel, which consists of a solid disk of mass 4.47 kg and radius 1.03 m. The system is released from rest. Over what vertical distance does the hanging mass move in 3.0 seconds? Ignore friction and drag forces, and assume that the string does not slip. Hint: If the string had 0 length, it would be obvious that the point mass contributes Ipt = mR² to the total rotational inertia, since the point mass would be directly stuck on the outside of the pulley. What's the difference if the string has nonzero length, so that the point mass hangs below the pulley as in the diagram? None at all! The pulley can't tell the difference between a point mass attached to it by a 0 length string or a 20 meter long string. All it knows is that there's a point mass m attached to its outer edge.
