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...

An air puck of mass 0.23 kg is tied to a string and allowed to revolve in a circle of radius 1.2 m on a frictionless horizontal table. The other end of the string passes through a hole in the center of the table, and a mass of 0.9 kg is tied to it. The suspended mass remains in equilibrium while the puck on the tabletop revolves. a) What is the tension in the string? (b) What is the force...

Object rotating on a string of changing length. A small mass m attached to the end of a string revolves in a circle on a friction-less tabletop. The other end of the string passes through a hole in the table. Initially the mass revolves with a speed 2.4 m/s in a circle of radius 0.80 m. The string is then pulled slowly through the hole so that the radius i reduced to 0.48 m. The final speed is 4.0 m/s...

A small block on a frictionless, horizontal surface has a mass of 2.60×10−2 kg . It is attached to a massless cord passing through a hole in the surface (the figure (Figure 1)). The block is originally revolving at a distance of 0.300 m from the hole with an angular speed of 1.65 rad/s . The cord is then pulled from below, shortening the radius of the circle in which the block revolves to 0.150 m. Model the block as...

A small block on a frictionless, horizontal surface has a mass
of 0.0260 kg. It is attached to a massless cord passing through a hole in the
surface (see figure below). The block is originally revolving at a
distance of 0.320 m from the hole with an angular speed of 1.90rad/s.
The cord is then pulled from below, shortening the radius of the
circle in which the block revolves to 0.160 m. Model the block as a particle.(a) Is angular...
