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!)

A small mass m attached to the end of a string revolves in a circle on...
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...

A small block on a frictionless horizontal surface has a mass of
0.0280 kg . It is attached to a massless cord passing through a
hole in the surface. (See the figure below (Figure 1) .) The block
is originally revolving at a distance of 0.310 m from the hole with
an angular speed of 1.80 rad/s . The cord is then pulled from
below, shortening the radius of the circle in which the block
revolves to 0.115 m ....

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 ball with mass m is attached to the end of a flagpole as shown in the figure below. The flagpole is connected to the side of a building at point P, has a length l, and makes an angle with the x-axis. (Consider the +x-direction to be to the right, the +y-direction upward, and the +z-direction to be out of the page.) At time t = 0, the ball becomes loose and begins to fall off of the flagpole...
