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 small 0.270-kg object moves on a frictionless horizontal table in a circular path of radius 1.70 m. The angular speed is 9.60 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 102 N, what is the...

A small 0.501-kg object moves on a frictionless horizontal table in a circular path of radius 1.16 m. The angular speed is 5.51 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 112 N, what is the...

4. A ball of mass m is on a frictionless table. A string is attached to the ball goes through a hole as shown. A mass M is hung from the string. M If the ball is originally a distance l from the hole, what angular velocity must it be given to the mass m so that the mass M will remain at rest? If the mass M is pulled down so that the ball goes in a circle of...

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: An inverted "V" is made of uniform boards and weighs 191 N. Each side has the same length and makes a 30.0° angle with the vertical, as the drawing shows. Find the magnitude of the static frictional force that acts on the lower end of each leg of the "V." B: A small 0.542-kg object moves on a frictionless horizontal table in a circular path of radius 1.31 m. The angular speed is 6.33 rad/s. The object is attached...

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) X M's angular momentum at y is .... that at x M's angular velocity at y is four times that at x M's...

A puck of mass m on a horizontal, frictionless table is connected to a string that passes through a small hole in the table. The puck is set into circular motion of radius R, at which time its speed is vi. If the string is pulled from the bottom so that the radius of the circular path is decreased to r, what is the expression for the final speed vf of the puck?

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...
