An object of mass m is on a frictionless table rotating with a given tangential speed vo with a radius of string ri. The string goes down through a hole (no friction) in the table where a given applied force, FA pulls down on the string a given distance d. Then, the object still keeps rotating but in a smaller and smaller circle. Find the final speed of the object after the rope was pulled down the distance d.

A mass of 0.875 kg, on a frictionless table, is attached to a string which passes through a hole in the table. The hole is at the center of a horizontal circle in which the mass moves with constant speed. The radius of the circle is 0.520 m and the speed of the mass is 17.0 m/s. It is found that drawing the string down through the hole and reducing the radius of the circle to 0.370 m has the...

A puck on a frictionless air-hockey table has a mass of 0.0500kg and is attached to a cord passing downward through a hole in the table. The puck is originally revolving at a distance of 0.300m from the hole with an angular speed of 2.50 rad/s. the cord is then pulled from below l, shortening the puck' s radius to 0.100m. what is the buck's new angular speed?

A small mass M attached to a string slides in a circle (x) on a frictionless horizontal table, with the force F providing the necessary tension (see figure). The force is then increased slowly and then maintained constant when M travels around in circle (y). The radius of circle (x) is twice the radius of circle (y). Answer can be true,false,less than, greater than, equal to (if you could leave an explanation that would be great!) M's angular velocity at...

A small mass m attached to the end of a string revolves in a circle on a frictionless tabletop. The other end of the string passes through a hole in the table (Fig. 8-62). Initially, the mass revolves with a speed vi = 2.4 m/s in a circle of radius ri =0.80 m. The string is then pulled slowly through the hole so that the radius is reduced to r2 0.48 m. What is the speed, 2, of the m...
